Speed Control Transfer Function 7.3.3 Motor Direction Change The DRV10964 can be easily configured to drive the motor in either direction by setting the input on the FR (Forward Reverse) pin to a logic 1 or logic 0 state. The direction of commutation as described by the commutation sequence is illustrated in Table 1. Table 1.

The output provided on this pin is configured by applying a logic signal to the FGS pin. The formula to determine the speed of the motor is: IF FGS = 0, RPM = (FREQFG × 60)/number of pole pairs IF FGS = 1, RPM = (FREQFG × 60 × 3)/number of pole pairs (2) (3) During Open Loop Acceleration the FG pin will provide an indication of the frequency of the signal which is driving the motor. The lock condition of the motor is not known during Open Loop Acceleration so it is possible that the FG could be toggling during this time even though the motor is not moving. The FG pin has built in short circuit protection, which limits the current in the event that the pin is shorted to VCC. The current will be limited to ISC_FG. 7.3.4.1 Tach Feedback During Spin Down The DRV10964 will provide feedback on the FG pin during spin down of the motor. Figure 7 illustrates the behavior of the FG output. When DRV10964 PWM input is at 0% DRV10964 will provide the output of the U phase comparator on the FG pin until the motor speed drops below 10 Hz. When the motor speed is below 10 Hz the device will enter into the Sleep state and the FG output will be held at a constant value based on the last BEMF zero cross detection. Closed Loop Operation FG = defined by FGS Command PWM = 0% Wait for Motor to Stop FG = U to CT BEMF comparator Speed < 10 Hz Sleep FG = 0 or 1 (will not toggle) Figure 7. TACH Feedback on Spin Down 7.3.5 Lock Detection When the motor is locked by some external condition the DRV10964 will detect the lock condition and will take action to protect the motor and the device. The lock condition must be properly detected whether it occurs as a result of a slowly increasing load or a sudden shock. The DRV10964 reacts to lock conditions by stopping the motor drive. To stop driving the motor the phase outputs are placed into a high impedance state. To prevent the current which is flowing in the motor from being returned to the power supply (VCC) the DRV10964 uses an Ant-Voltage Surge feature. For more information on this feature, see Anti-Voltage Surge (AVS). After successfully transitioning into a high impedance state as the result of a lock condition the DRV10964 will attempt to restart the motor after tOFF_LOCK seconds. The DRV10964 has a comprehensive lock detect function which includes 5 different lock detect schemes. Each of these schemes detects a particular condition of lock as illustrated in Figure 8. 10 Submit Documentation Feedback Copyright © 2016, Texas Instruments Incorporated Product Folder Links: DRV10964 DRV10964 www.ti.com SLDS227 – MARCH 2016 No motor Frequency Overflow BEMF abnormal Tri-state and Restart Logic Accelerate abnormal Speed abnormal Figure 8. Lock Detect The behavior of each lock detect scheme is described in the following sections. 7.3.5.1 Lock0: No Motor The Phase U current is checked after transitioning from open loop to closed loop. If Phase U current is not greater than 50mA then the motor is not connected. This is reported as a locked condition. 7.3.5.2 Lock1: Frequency Overflow For most applications the maximum electrical frequency of the motor will be less than 3 kHz. If the motor is stopped then the BEMF voltage will be zero. Under this condition, when the DRV10964 device is in the closed loop mode, the sensor less control algorithm will continue to accelerate the electrical commutation rate even though the motor is not spinning. A lock condition is triggered if the electrical frequency exceeds 3 kHz. 7.3.5.3 Lock2: BEMF Abnormal For any specific motor, the integrated value of BEMF during half of an electrical cycle will be a constant as illustrated by the shaded green area in Figure 9. This is true regardless of whether the motor runs fast or slow. The DRV10964 monitors this value and uses it as a criterion to determine if the motor is in a lock condition. The DRV10964 uses the integrated BEMF to determine the Kt value of the motor during the initial motor start. Based on this measurement a range of acceptable Kt values is established. This range is between 1/2 x Kt and 4 x Kt During closed loop motor operation the Ktc value is continuously updated. If the calculated Ktc goes beyond the acceptable range a lock condition is triggered. This is illustrated in Figure 10. Figure 9. BEMF Integration Submit Documentation Feedback Copyright © 2016, Texas Instruments Incorporated Product Folder Links: DRV10964 11 DRV10964 SLDS227 – MARCH 2016 www.ti.com 4 x Kt Ktc Kt 0.5 x Kt Lock detect Figure 10. Abnormal Kt Lock Detect 7.3.5.3.1 Lock 3: Accelerate Abnormal This lock condition is active when the DRV10964 device is operating in the closed loop mode. When the closed loop commutation rate becomes lower than 1/2 of the previous commutation period then this is an indication that the motor is not moving. Under this condition the accelerate abnormal condition will be triggered. 7.3.5.4 Lock4: Speed Abnormal If the motor is in normal operation the motor BEMF will always be less than the voltage applied to the phase. The DRV10964 sensorless control algorithm is continuously updating the value of the motor BEMF based on the speed of the motor and the motor Kt as shown in Figure 11. If the calculated value for motor BEMF is higher than the applied voltage (U) for a certain period of time (tON_LOCK) then there is an error in the system. The calculated value for motor BEMF is wrong or the motor is out of phase with the commutation logic. When this condition is detected a lock detect is triggered. Rm M U BEMF = kt * speed If speed > U / kt Lock is triggered. Figure 11. BEMF Monitoring 7.3.6 Short Circuit Current Protection The short circuit current protection function shuts off drive to the motor by placing the motor phases into a high impedance state if the current in any motor phase exceeds the short circuit protection limit ISHT. The DRV10964 device will go through the initialization sequence and will attempt to restart the motor after the short circuit condition is removed. This function is intended to protect the device and the motor from catastrophic failure when subjected to a short circuit condition. 7.3.7 Anti-Voltage Surge (AVS) Under normal operation the DRV10964 acts to transfer energy from the power supply to the motor to generate torque, which results in angular rotation of the motor. Under certain conditions, however, energy which is stored in the motor in the form of inductive energy or angular momentum (mechanical energy) can be returned to the power supply. This can happen whenever the output voltage is quickly interrupted or whenever the voltage applied to the motor becomes less than the BEMF voltage generated by the motor. The energy which is returned to the supply can cause the supply voltage to increase. This condition is referred to as voltage surge. 12 Submit Documentation Feedback Copyright © 2016, Texas Instruments Incorporated Product Folder Links: DRV10964 DRV10964 www.ti.com SLDS227 – MARCH 2016 The DRV10964 includes an anti-voltage-surge (AVS) feature which prevents energy from being transferred from the motor to the power supply. This feature helps to protect the DRV10964 as well as any other components that are connected to the power supply (VCC). 7.3.7.1 Protecting Against the Return of Mechanical Energy Mechanical energy is typically returned to the power supply when the speed command is abruptly decreased. If the voltage applied to the phase becomes less than the BEMF voltage then the motor will work as a generator and current will flow from the motor back to VCC. This is illustrated in Figure 12. To prevent this from happening, the DRV10964 buffers the speed command value and limits the rate at which it is able to change. The AVS function acts to ensure that the effective output amplitude (U) is maintained to be larger than the BEMF voltage. This prevents current from becoming less than zero. The value of BEMF used to perform this function is calculated by the motor Kt and the motor speed. Rm I M U = BEMF + I * Rm If U < BEMF, I BEMF, I>0. Figure 12. Mechanical AVS 7.3.7.2 Protecting Against the Return of Inductive Energy When the DRV10964 suddenly stops driving the motor, the current which is flowing in the motor’s inductance will continue to flow. It flows through the intrinsic body diodes in the mosfets and charges VCC. An example of this behavior is illustrated by the two pictures in the top half of Figure 13. When the driver is active, the current flows from S1 to the motor and then to S6 and is returned to ground. When the driver is placed into a high impedance (tri-state) mode, the current goes flows from ground through the body diode of S2 to the motor and then through the body diode of S5 to VCC. The current will continue to flow through the motor’s inductance in this direction until the inductive energy is dissipated. Figure 13. Inductive AVS The lower two pictures in Figure 13 illustrate how the AVS circuit in the DRV10964 device prevents this energy from being returned to the supply. When the AVS condition is detected the DRV10964 device will act to turn on the low side device designated as S6. This allows the current flowing in the motor inductance to be returned to ground instead of being directed to the VCC supply voltage.

Motor operation will resume when the junction temperature becomes lower than TSD - TSD_HYS. 7.3.9 Undervoltage Protection The DRV10964 contains an undervoltage lockout feature, which prevents motor operation whenever the supply voltage (VCC) becomes too low. Upon power up, the DRV10964 will operate once VCC rises above VUVLO_H. The DRV10964 will continue to operate until VCC falls below VUVLO_L. 7.3.10 CONFIG Configuration The CONFIG pin provides an option for selecting the open loop to closed loop threshold. This is accomplished with the selection of a resistor divider between VCC and GND which is connected to the CONFIG pin. See Electrical Characteristics. 7.4 Device Functional Modes 7.4.1 Spin up Settings 7.4.1.1 Motor Kt and Rm DRV10964 utilizes information about the motor's torque constant and resistance to control motor timing. These parameters are measured during the initial motor spin up as shown in Figure 14. 7.4.1.2 Motor Start DRV10964 will start the motor using a procedure which is illustrated in Figure 14. Power On Calibration Align 40 ms Resistance Measurement Open Loop Accelerate Wait TOFF_LOCK Coasting Close Loop Kt Measurement Closed Loop Lock Detected Figure 14. DRV10964 Initialization and Motor Start-up Sequence 7.4.1.3 Initial Speed Detect (ISD) The ISD function is used to identify the initial condition of the motor. Phase-to-phase comparators are used to detect the zero crossings of the motor’s BEMF voltage while it is coasting (motor phase outputs are in high-impedance state). Figure 15 shows the configuration of the comparators. 14 Submit Documentation Feedback Copyright © 2016, Texas Instruments Incorporated Product Folder Links: DRV10964 DRV10964 www.ti.com SLDS227 – MARCH 2016 Device Functional Modes (continued) 60 degrees ± V + U + ± W Figure 15. Initial Speed Detect Function The motor speed is determined by measuring the time between two rising edges of either of the comparators. If neither of the comparator outputs toggle for a given amount of time (80 ms), the condition is defined as stationary and the Align state will begin. If the comparators are toggling at a speed that is greater than this threshold then the DRV10964 will wait for the motor to slow down until the toggling is less than the threshold and it can be treated as stationary. 7.4.1.4 Align To align the rotor to the commutation logic the DRV10964 applies a 50% duty cycle on phases V and W while holding phase U at GND. This condition is maintained for 0.64 seconds. In order to avoid a sudden change in current that could result in undesirable acoustics the 50% duty cycle is applied gradually to the motor over 0.3 seconds. 7.4.1.5 Handoff and Closed Loop When the motor accelerates to the velocity defined by the voltage applied to the CONFIG pin, commutation control transitions from open loop mode to closed loop mode. The commutation drive sequence and timing is determined by the internal control algorithm and the applied voltage is determined by the PWM commanded duty cycle input. The selection of handoff threshold can be determined by experimental testing. The goal is to choose a handoff threshold that is as low as possible and allows the motor to smoothly and reliably transition between the open loop acceleration and the closed loop acceleration. Normally higher speed motors (maximum speed) require a higher handoff threshold because higher speed motors have lower Kt and as a result lower BEMF. Table 2 shows the configurable settings for the handoff threshold. Maximum speed in electrical hertz are shown as a guide to assist in identifying the appropriate handoff speed for a particular application. Table 2.

The user must place a 2.2-μF ceramic capacitor rated for VCC as close as possible to the VCC and GND pin. 10 Layout 10.1 Layout Guidelines The package uses an exposed pad to remove heat from the device. For proper operation, this pad must be thermally connected to copper on the PCB to dissipate heat. On a multi-layer PCB with a ground plane, this can be accomplished by adding a number of vias to connect the thermal pad to the ground plane. On PCBs without internal planes, copper area can be added on either side of the PCB to dissipate heat. If the copper area is on the opposite side of the PCB from the device, thermal vias are used to transfer the heat between top and bottom layers. For details about how to design the PCB, refer to TI application report, PowerPAD™ Thermally Enhanced Package (SLMA002), and TI application brief, PowerPAD™ Made Easy (SLMA004), available at www.ti.com. In general, the more copper area that can be provided, the more power can be dissipated. 10.2 Layout Example 2.2 uF GND VCC 100k 10 PWM FG 1 100k 9 CONFIG FGS 2 VCC 3 GND (PPAD) 8 FR W 4 7 U GND 5 6 V Figure 21.
