Automotive Relay Driver Includes Regulator

Designed for relay-based applications requiring a microprocessor, the A2550 automotive-grade relay driver integrates a voltage regulator, watchdog and reset, and three low-side DMOS relay-driver outputs. The DMOS drivers power relay coils with up to 250 mA each. Each driver integrates voltage clamps that survive load-dump pulses up to 48V. Additionally, the 5V linear regulator provides 40 mA of output current with a tolerance of 2% over the operating temperature range. Price for the A2550 is $1 each/1,000.
