Quad-Gated Inverting Power Driver For

Description

The CA3242 quad-gated inverting power driver contains four

gate switches for interfacing low-level logic to inductive and

resistive loads such as: relays, solenoids, AC and DC

motors, heaters, incandescent displays, and vacuum ﬂuo-

rescent displays.

Output overload protection is provided when the load current

(approximately 1.2A) causes the output V

above 1.3V. A built-in time delay, nominally 25 s, is provided

during output turn-on as output drops from V

output will be shut down by its protection network without

affecting the other outputs. The corresponding Input or

Enable must be toggled to reset the output protection circuit.

Steering diodes in the outputs in conjunction with external

zener diodes protect the IC against voltage transients due to

switching inductive loads.

To allow for maximum heat transfer from the chip, the four

center leads are directly connected to the die mounting pad.

In free air, junction-to-air thermal resistance (R

(typical). This coefﬁcient can be lowered by suitable design

of the PC board to which the CA3242 is soldered.
