3 / 36 page Analog Integrated Circuit Device Data Freescale Semiconductor 3 33970 PIN CONNECTIONS PIN CONNECTIONS Figure 3. 33970 Pin Connections Table 1. 33970 Pin Definitions A functional description of each pin can be found in the Functional Pin Description section beginning on page 10. Pin Number Pin Name Pin Function Formal Name Definition 1 2 3 4 COS0+ COS0 − SIN0+ SIN0 − Output H-Bridge Outputs 0 Each pin is the output pin of a half bridge, designed to source or sink current. 5–8, 17–20 GND Ground Ground These pins serve as the ground for the source of the low-side output transistors as well as the logic portion of the device. 9 CS Input Chip Select This pin is connected to a chip select output of a LSI IC. 10 SCLK Input Serial Clock This pin is connected to the SCLK pin of the master device and acts as a bit clock for the SPI port. 11 SO Output Serial Output This pin is connected to the SPI Serial Data Input pin of the master device, or to the SI pin of the next device in a daisy chain. 12 SI Input Serial Input This pin is connected to the SPI Serial Data Output pin of the master device from which it receives output command data. 13 RTZ Output Multiplexed Output This is a multiplexed output pin, for the non-driven coil, during a Return to Zero (RTZ) event. 14 VDD Input Voltage This SPI and logic power supply input will work with 5.0 V supplies. 15 RST Input Reset This input has an internal active pull-up. 16 VPWR Input Battery Voltage Power supply. 21 22 23 24 SIN1 − SIN1+ COS1 − COS1+ Output H-Bridge Outputs 1 Each of these pins are the output pin of a half bridge, designed to source or sink current. COS0+ COS0- SIN0+ SIN0- GND GND GND CS SCLK SO SI 1 2 3 4 5 6 7 8 9 10 11 12 24 23 22 21 20 19 18 17 16 15 14 13 COS1+ COS1- SIN1+ SIN1- GND GND GND VPWR RST VDD RTZ GND GND |
