Pin description Pin# Name Type Function 1PWM3 D(1) PWM output. Connect to multi-phase channel 3 external driver PWM input. During nor- mal operation the device is able to manage HiZ status by setting and hold- ing the PWMx pin to the predefined fixed voltage. See Table 7 for phase number programming. 2 PWM2 D PWM output. Connect to multi-phase external drivers PWM input. These pins are also used to configure HiZ levels for compatibility with drivers and DrMOS. Dur- ing normal operation the device is able to manage HiZ status by setting and holding the PWMx pin to the predefined fixed voltage. 3PWM1 D 4 PHASE A Connect through resistor divider to multi-phase channel1 switching node. n/a NC - Not internally bonded 5 VR_RDY D VR Ready. Open drain output set free after SS has finished in multi-phase section and pulled low when triggering any protection on multi-phase sec- tion. Pull up to a voltage lower than 3.3 V (typ.), if not used it can be left floating. |
