Description

The CA3273 is a power IC equivalent of a P-N-P pass transistor 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.
