The LMP92064 is a precision, low-side, digital current sensor and voltage monitor with a digital SPI interface. The LMP92064 features a current sense and a voltage sense channel, which are sampled simultaneously by independent 12-bit ADC converters. 1.1 LMP92064EVM Kit Contents Table 1 lists the contents of the LMP92064EVM kit and Figure 1 shows all the included hardware. The EVM board contains one LMP92064 device in a low-side configuration for current sensing and voltage monitoring. The EVM comes pre-assembled with a 0.05Ω sense resistor (0.5W), bypass capacitors, test points and connection terminals. The USB2ANY board and the adaptor are required to communicate with the EVM from a PC running the evaluation software. Table 1.

These turrets should be used to connect an external voltage source to power the analog circuitry. There is a 10 µF tantalum capacitor and two ceramic capacitors with values of 0.1 µF and 10 pF on the VDD line. The analog supply should be operated between 4.5V and 5.5V. 2.2 Digital Power Supply Input – VDIG and DGND The digital supply pin of the device is connected to the VDIG terminal of the EVM and the digital ground plane of the EVM is connected to the DGND terminal. These turrets should be used to connect an external voltage source to power the digital circuitry. There is a 10µF tantalum capacitor and two ceramic capacitors with values of 0.1 µF and 10 pF on the VDIG line. The digital supply should be operated between 4.5V and 5.5V. Figure 2. Power Supply Terminals 2.3 Current Sense Resistor and Sense Terminals The EVM board has placeholders for a current sense resistor, providing options for either through-hole or surface mount resistors. The large pads are bare copper to allow mounting various sizes and shapes of resistor, as well as providing heat dissipation. The board comes pre-assembled with a 0.05Ω sense resistor (0.5W). Figure 3. Rsense Terminals The larger inner holes are for optional pin socket receptacles to allow easy swapping of through-hole resistors for prototyping. 4 LMP92064EVM User's Guide SNOU123 – JUNE 2013 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated LMP92064EVM Connectors and Components www.ti.com For off-board current sense resistors, the sense lines can be connected to the SENSE+ and SENSEterminals (removing the on-board sense resistor). It is recommended for these wires to be twisted to prevent noise and electromagnetic interference (EMI) pickup. Load ground currents should be kept off the board. Load current should be returned directly to the power supply terminals and not through the evaluation board grounds. 2.4 Voltage Sense Resistors and Terminals The EVM provides two resistors, R11 and R12, as means of sensing the voltage on a bus connected to the BUS+ terminal. The resistor values of R11 and R12 should be selected according to the voltage on the bus that is to be monitored, considering the maximum input range of the Voltage Sensing Channel, which is 2.048V. ( INVP − INVG ) = VBUS × R11 ≤ 2.048V R11 + R12 (1) The EVM comes pre-assembled with values of R11 = 2kΩ and R12 = 30 kΩ. Figure 4. Bus Voltage Divider 2.5 Optional Input Filtering The optional R1, R2, R3 and R4 resistor pads are provided to add, in conjunction with C1 and C2, EMI/noise filtering to the input. Series resistors or series inductors can optionally be connected to these pads. To maintain a continuous solid copper path between the shunt and the inputs of the amplifier, the resistor pads have shorting traces across them. To use these pads, the shorting traces must be cut before installing the resistors. Figure 5. R1, R2, R3 and R4 shorting traces must be cut before use SNOU123 – JUNE 2013 Submit Documentation Feedback LMP92064EVM User's Guide Copyright © 2013, Texas Instruments Incorporated 5 LMP92064EVM Connectors and Components www.ti.com To maintain accuracy, these resistors should be of equal value and well matched, as they are in series with the device’s internal resistors and will affect the device's specifications. The values of these resistors should be kept as low as possible and should not exceed a few hundred ohms. Pads C1 and C2 are provided for optional EMI rejection. For RF/EMI protection, values in the 10 pF to 100 pF range are recommended. It is also possible to use the resistor pairs R1/R2 and R3/R4 with the capacitors C1 and C2 to create a first-order low-pass filter in the signal path. Keep in mind that, creating an AC filter of reasonable cut-off frequency with resistor values below a few hundreds of ohms, the capacitor values will become quite large. Figure 6. Optional Input Filtering Capacitors 2.6 Input Sense Test Points – TP4 and TP5 These standard 0.1” headers allow probing the input signals or applying test voltages. TP4 is connected to the Current Sensing Channel and TP5 is connected to the Voltage Sensing Channel. Figure 7.

The reference pin is not intended to drive other circuitry. Figure 8. Reference test point and reset switch 2.8 Reset Switch – SW1 This switch is used to perform a hardware reset on the LMP92064. The combination of R10 and C10 is used to smoothen the falling edge of the reset pulse generated when releasing the switch. 2.9 Serial Peripheral Interface (SPI) Bus Test Point – DEBUG TP8 This standard 0.1” header allows probing the SPI bus. The SPI bus consists of an active-low chip select (CSB) line, a serial clock (SCLK) line, a serial data output (SDO) line and a serial data input (SDI) line. There is an additional reserved line (RSV) that is not part of the SPI interface. Figure 9.

Refer to the Schematic for the component values. The value of these resistors should be limited to below a few hundred ohms, otherwise the digital communication may become unreliable. Figure 10. Series resistors on digital lines 2.11 Interface Connector – J8 J8 is used to connect the LMP92064EVM to the USB2ANY board. The interface is used to access the device registers and to read the conversion data from the LMP92064. An adaptor board is required between the EVM and the USB2ANY board. Figure 11. GPSI16 Interface Connector 2.12 Ground Test Points – GND TPx There are ground (GND) test points distributed around the board for ease of probing: TP1, TP2, TP3, TP7 and TP9. 8 LMP92064EVM User's Guide SNOU123 – JUNE 2013 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated LMP92064EVM Software Installation www.ti.com 3 LMP92064EVM Software Installation The latest software version for the LMP92064EVM can be downloaded from the Texas Instruments website at http://www.ti.com/product/lmp92064.
