CA3273
High-Side Driver
Description
The CA3273 is a power IC equivalent of a P-N-P pass tran-
sistor operated as a high-side-driver current switch in either
the saturated (ON) or cutoff (OFF) modes. The CA3273
incorporates circuitry to protect the pass currents, excessive
input voltage, and thermal overstress. The high-side driver is
intended for general purpose, automotive and potentially
high-stress applications. If high-stress conditions exist, the
use of an external zener diode of 35V or less between sup-
ply and load terminals may be required to prevent damage
due to severe conditions (such as load dump, reverse bat-
tery and positive or negative transients). The CA3273 is
designed
to
withstand
a
(VBAT = 13V) condition without permanent damage to the
IC. The CA3273 is supplied in a modified 3-lead TO-202
plastic power package.
