12.3. Functional Description
The Application Specific Power Drivers (ASPD, Figure 12-1) module handles power driving for power control
applications.
The PAC5210 contains only medium-voltage open-drain drivers (OMx pins). The open-drain drivers provide
activation control for relays, LEDs, buffers, and other loads.

The ASPD includes built-in configurable fault protection for the internal gate drivers. On the PAC5210, the
protection signals ENHS1 and ENHS2 are provided for external circuitry driver fault protection.
12.3.1. Open-Drain Drivers
The OMx pin is a 23V open-drain driver output controlled by a register bit. The OMx is capable of driving 40mA.
The OMx pin is switched to VSSP with 17Ω impedance in the on state when the corresponding bit is '1', and is in
the high-impedance off state when the corresponding bit is '0'.
