Summary
Quad-Gated Inverting Power Drivers with Fault Mode Diagnostic Flag Output July 1997
Description
The CA3272A and CA3292A are Quad-Gated Inverting Power Drivers for interfacing low-level logic to inductive and resistive loads such as: relays, solenoids, AC and DC motors and resistive loads such as incandescent lamps and other power drivers. Each output is an open collector protected power transistor driver. The CA3292A is similar to the CA3272A, except for an added collector-to-base Zener diode that provides over-voltage clamping protection on each power switching output. The CA3292A block diagram is shown for one switching channel with fault detection logic plus the output fault driver circuit for all four switching channels. The FAULT output pin provides a flag output when a fault condition occurs. All four Output Power Driver stages are shown in the Block Diagrams.
