Feature Description (continued)
7.2.3 CAN
The CAN data from CAN control logic is transmitted to other systems through the CAN bus. The receiver
compares the CAN_H–CAN_L voltage levels against an internally generated reference and the result is output
through CAN_TX. It has overcurrent protection, shown in Figure 6.

7.2.4 Charge Pump
The charge pump block generates the supply for high-side and low-side pre-drivers to maintain the gate voltage
on the external FETs. External storage cap (CCP) and bucket caps (C1, C2) are used to support pre-driver slope
and switching frequency requirements. R1 and R2 can reduce switching current if required. The charge pump
has a voltage supervisor for over and undervoltage, and a selectable stop condition for pre-drivers.
