Quad Power Output Driver Shoots For Automotive Market

Designed to withstand the harsh and noisy environments found in automotive, industrial and telecommunications applications, the CS1112 quad power output driver IC uses proprietary PowerSense circuit technology that improves die density and increases power efficiencies to minimize chip power consumption. The chip integrates four protected DMOS low-side drivers controlled either through a SPI port or its associated parallel input.
Output protection features include over-current and open load detection and inductive flyback clamps. The device also features a sleep mode where it draws only 2 µA of bias current. In a 24-lead SOIC package, the device is priced at $2.36 each/10,000.
