Pin Number Pin Name Pin Function Formal Name Definition 1, 3, 5, 50, 52, 54 VDSNS1- VDSNS6 Input Drain Voltage Sense The VDSNS pin is used to monitor the drain voltage of the external MOSFET. 2, 4, 6, 49, 51, 53 GD1-GD6 Output Gate Driver Output The GD pin provides gate drive for an external MOSFET 7 48 VSSNS456 VSSNS123 Input Source Voltage Sense The VSSNS pins are used to monitor the source voltage of the external MOSFETS. 8 LRFDBK Output Load Resistance Feedback The LRFDBK pin is an operational amplifier output. 9 SI Input Serial Input Data The SI input pin is used to receive serial data from the MCU. The serial input data is latched on the rising edge of SCLK, and the input data transitions on the falling edge of SCLK. 10 SCLK Input Serial Clock Input The SCLK input pin is used to clock in and out the serial data on the SI and SO Pins while being addressed by the CS. 11 CS Input Chip Select The Chip Select input pin is an active low signal sent by the MCU to indicate that the device is being addressed. This input requires CMOS logic levels and has an internal active pull up current source. 12 P1 Input Input One Input control of OSS output 1. When configured via the SPI, P1 input may be used to control OSS output 1 and output 2 in parallel. 13 P3 Input Input Three Input control of OSS output 3. When configured via the SPI, P3 input may be used to control OSS output 3 and output 4 in parallel. 14 P5 Input Input Five Input control of OSS output 5. When configured via the SPI, P5 input may be used to control OSS output 5 and output 6 in parallel. 54 40 35 34 33 32 31 30 29 28 39 38 37 36 47 46 45 44 43 42 41 51 50 49 48 53 52 1 15 20 21 22 23 24 25 26 27 16 17 18 19 8 9 10 11 12 13 14 4 5 6 7 2 3 VDSNS4 GD4 VDSNS5 GD5 VDSNS6 GD6 VSSNS456 LRFDBK SI SCLK CS P1 P3 P5 P7 PWM1 PWM2 PWM3 PWM4 PWM5 PWM6 CCD2_GND CCD2_OUT CCD2_REC EN RI_REF CCD1_OUT VDSNS3 GD3 VDSNS2 GD2 VDSNS1 GD1 VSSNS123 REXT PGND1 OUT1 PGND2 OUT2 OUT3 OUT4 OUT5 PGND OUT6 OUT7 OUT8 DEFAULT SO VDD VCAL GND VPWR CCD1_GND CCD1_REC |
