Product Summary

The A2557KLB-T is a protected quad low-side driver with fault detection and sleep mode. It has been specifically designed to provide cost-effective solutions to relay-driving applications with up to 300 mA drive current per channel. TheA2557KLB-T may also be used for driving incandescent lamps in applications where turn-on time is not a concern. Each of the four outputs will sink 300 mA in the on state. The outputs have a minimum breakdown voltage of 60 V and a sustaining voltage of 40 V.
