Place a decoupling capacitor close to the controller IC. Also used in UVLO1 fault generation – if VIN1 falls below the user programmed limit, all channels are shut down. The VIN1 pin needs to be tied to VIN2 on the board with a short trace. VIN2 38 If the VIN2 pin voltage falls below the user programmed UVLO VIN2 level all channels are shut down. The VIN2 pin needs to be tied to VIN1 on the board with a short trace. VCCA 37 Output of the internal 5V LDO. This voltage is internally used to power analog blocks. This pin should be bypassed with a minimum of 4.7uF to AGND VCCD 26 Gate Drive input voltage. This is not an output voltage. This pin can be connected to VCCA to provide power for the Gate Drive. VCCD should be connected to VCCA with the shortest possible trace and decouple with a minimum 1µF capacitor. Alternatively, VCCD could be connected to an external supply (not greater than 5V). PGND14 36,31,16,21 Power Ground. Ground connection for the low side gate driver. Connect at low side FET source. AVDD 1 Output of the internal 1.8V LDO. This pin should be bypassed with a minimum of 2.2uF to DGND DVDD 2 Input for powering the internal digital logic. This pin should be connected to AVDD. DGND 10 Digital Ground. Connect this pin to the ground plane at the exposed pad with a separate trace. AGND 11 Analog Ground. Connect this pin to the ground plane at the exposed pad with a separate trace |
