Input on GVDD provides the gate bias voltage for the low-side MOSFETs. The high voltage is generated using bootstrap capacitor and GVDD supply. The half-bridge gate drivers can be used in combination to drive a three-phase motor or separately to drive other types of loads. 8.3.1.1 Gate Drive Timings 8.3.1.1.1 Propagation Delay The propagation delay time (tpd) is measured as the time between an input logic edge to a detected output change. This time has two parts consisting of the input deglitcher delay and the delay through the analog gate drivers. The input deglitcher prevents high-frequency noise on the input pins from affecting the output state of the gate drivers. The analog gate drivers have a small delay that contributes to the overall propagation delay of the device. 8.3.1.1.2 Deadtime and Cross-Conduction Prevention In the DRV8300, high- and low-side inputs operate independently, with an exception to prevent cross conduction when high and low side are turned ON at same time. The DRV8300 turns OFF high- and low- side output to prevent shoot through when high- and low-side inputs are logic high at same time. The DRV8300 also provides deadtime insertion to prevents both external MOSFETs of each power-stage from switching on at the same time. In devices with DT pin (QFN package device), deadtime can be linearily adjusted between 200 nS to 2000 nS by connecting resistor between DT and ground. When DT pin left floating, fixed deadtime of 200 nS (Typical value) is inserted. The value of resistor can be caculated using following equation. 4&6 (GÀ) = &A=@PEIA (J5) 5 In device without DT pin (TSSOP package device), fixed deadtime of 200 nS (Typical value) is inserted to prevent high and low side gate output turning on at same time.

In devices with MODE pin (QFN package device), the DRV8300 provides option of GLx output inverted or non-inverted compared to polarity of signal on INLx pin. When MODE pin is left floating INLx is configured to be in non-inverting mode and GLx output is in phase with INLx (see Figure 8-4), whereas when MODE pin is connected to GVDD, GLx output is out of phase with inputs (see Figure 8-5). In devices without MODE pin (TSSOP package device), there are different device option available for inverting and non inverting inputs (see Section 5) INHx INLx GHx GLx DT DT DT Figure 8-4.

INHx and INLx has passive pull down, so when inputs are floating the output of gate driver will be pulled low. Figure 8-7 shows the input structure for the logic level pin inverted INLx.

If at any time the supply voltage on the BSTx pin falls lower than the VBSTUV threshold, high side external MOSFETs of that particular phase is disabled by disabling (Hi-Z) GHx pin. Normal operation starts again when the BSTUV condition clears and low to high PWM edge is detected on INHx input on the same phase BSTUV was detected. BSTUV protection ensures that high side gate driver are not switched when BSTx pin has lower value. 8.3.3.2 GVDD Undervoltage Lockout (GVDDUV) If at any time the voltage on the GVDD pin falls lower than the VGVDDUV threshold voltage, all of the external MOSFETs are disabled. Normal operation starts again GVDDUV condition clears. GVDDUV protection ensures that gate driver are not switched when GVDD input is at lower value. 8.4 Device Functional Modes Whenever the GVDD > VGVDDUVand VBSTX > VBSTUV the device is in operating (active) mode, in this condition gate driver output GHx and GLX will follow respective inputs INHx and INLx. 16 Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: DRV8300 DRV8300 www.ti.com SLVSFG5C – SEPTEMBER 2020 – REVISED FEBRUARY 2021 9 Application and Implementation Note Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness.

Design Parameters EXAMPLE DESIGN PARAMETER REFERENCE EXAMPLE VALUE - CSD19532Q5B MOSFET Gate Supply Voltage Gate Charge VGVDD 12 V QG 48 nC 9.2.2 Detailed Design Procedure Bootstrap Capacitor and GVDD Capacitor Selection The bootstrap capacitor must be sized to maintain the bootstrap voltage above the undervoltage lockout for normal operation. Equation 1 calculates the maximum allowable voltage drop across the bootstrap capacitor: ¿8$56: = 8)8&& F 8$116& F 8$5678 (1) =12 V – 0.85 V – 4.5 V = 6.65 V where • VGVDD is the supply voltage of the gate drive • VBOOTD is the forward voltage drop of the bootstrap diode • VBSTUV is the threshold of the bootstrap undervoltage lockout In this example the allowed voltage drop across bootstrap capacitor is 6.65 V. It is generally recommended that ripple voltage on both the bootstrap capacitor and GVDD capacitor should be minimized as much as possible. Many of commercial, industrial, and automotive applications use ripple value between 0.5 V to 1 V. The total charge needed per switching cycle can be estimated with Equation 2: 3616 = 3) + +.$5_64#05 B59 (2) =48 nC + 220 μA/20 kHz = 50 nC + 11 nC = 59 nC where • QG is the total MOSFET gate charge • ILBS_TRAN is the bootstrap pin leakage current • fSW is the is the PWM frequency The minimum bootstrap capacitor an then be estimated as below assuming 1V ΔVBSTx: %$56_/+0 = 3616W¿8 (3) $56: = 59 nC / 1 V = 59 nF The calculated value of minimum bootstrap capacitor is 59 nF. It should be noted that, this value of capacitance is needed at full bias voltage. In practice, the value of the bootstrap capacitor must be greater than calculated value to allow for situations where the power stage may skip pulse due to various transient conditions. It is recommended to use a 100 nF bootstrap capacitor in this example. It is also recommenced to include enough margin and place the bootstrap capacitor as close to the BSTx and SHx pins as possible. Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: DRV8300 19 DRV8300 www.ti.com SLVSFG5C – SEPTEMBER 2020 – REVISED FEBRUARY 2021 Note If device variants (DRV8300D) with integrated bootstrap diode are used with bootstrap capacitor value (CBSTx) above 1 μF, than current flowing through internal bootstrap diode needs to be limited. The local GVDD bypass capacitor must be greater than the value of bootstrap capacitor value (generally 10 times the bootstrap capacitor value). %)8&& R 10 × %$56: (4) = 10*100 nF= 1 μF For this example application choose 1 µF CGVDD capacitor. Choose a capacitor with a voltage rating at least twice the maximum voltage that it will be exposed to because most ceramic capacitors lose significant capacitance when biased. This value also improves the long term reliability of the system. Gate Resistance Selection The slew rate of the SHx connection will be dependent on the rate at which the gate of the external MOSFETs is controlled. The pull-up/pull-down strength of the DRV8300 is fixed internally, hence slew rate of gate voltage can be controlled with an external series gate resistor. In some applications the gate charge, which is load on gate driver device, is significantly larger than gate driver peak output current capability. In such applications external gate resistors can limit the peak output current of the gate driver. External gate resistors are also used to damp ringing and noise. The specific parameters of the MOSFET, system voltage, and board parasitics will all affect the final slew rate, so generally selecting an optimal value or configuration of external gate resistor is an iterative process. 9.2.3 Application Curves GHA GHA SHA SHA GLA GLA Figure 9-2.

A local bypass capacitor should be placed between the GVDD and GND pins. This capacitor should be located as close to the device as possible. A low ESR, ceramic surface mount capacitor is recommended. It is recommended to use two capacitors across GVDD and GND: a low capacitance ceramic surface-mount capacitor for high frequency filtering placed very close to GVDD and GND pin, and another high capacitance value surfacemount capacitor for device bias requirements. In a similar manner, the current pulses delivered by the GHx pins are sourced from the BSTx pins. Therefore, capacitor across the BSTx to SHx is recommended, it should be high enough capacitance value capacitor to deliver GHx pulses Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated Product Folder Links: DRV8300 21 DRV8300 www.ti.com SLVSFG5C – SEPTEMBER 2020 – REVISED FEBRUARY 2021 11 Layout 11.1 Layout Guidelines • • • • • • • • Low ESR/ESL capacitors must be connected close to the device between GVDD and GND and between BSTx and SHx pins to support high peak currents drawn from GVDD and BSTx pins during the turn-on of the external MOSFETs. To prevent large voltage transients at the drain of the top MOSFET, a low ESR electrolytic capacitor and a good quality ceramic capacitor must be connected between the high side MOSFET drain and ground. In order to avoid large negative transients on the switch node (SHx) pin, the parasitic inductances between the source of the high-side MOSFET and the source of the low-side MOSFET must be minimized. In order to avoid unexpected transients, the parasitic inductance of the GHx, SHx, and GLx connections must be minimized. Minimize the trace length and number of vias wherever possible. Minimum 10 mil and typical 15 mil trace width is recommended. Resistance between DT and GND must be place as close as possible to device Place the gate driver as close to the MOSFETs as possible. Confine the high peak currents that charge and discharge the MOSFET gates to a minimal physical area by reducing trace length. This confinement decreases the loop inductance and minimize noise issues on the gate terminals of the MOSFETs. In QFN package device variants, NC pins can be connected to GND to increase ground conenction between thermal pad and external ground plane.
