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 resis-
tive 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.
The ENABLE input is common to each of the four power
switches and when low, disables the FAULT output. From the
Input to Output, each switch is inverting. When IN is high, OUT
is low and the transistor switch is “ON” (conducting). The block
diagram shows the functional logic associated with fault detec-
tion. The Fault Sense circuit detects the IN and OUT states and
switches Q

pin. A resistive load from the FAULT pin to the power supply is
used to detect a fault as a low state. Both shorted and open
load conditions are detected.
Note: The CA3272A replaces the CA3272 for new designs.
Refer to the Fault Sink Current specifications when making
design changes. The CA3272A and CA3292A have increased
pull-down current drive from the FAULT output pin.
