Allegro MicroSystems A2557KLBTR is a 4-channel bipolar power driver IC in a 16-SOIC package. This device features fixed current limiting and over-temperature fault protection, with a status flag output for monitoring. Designed for low-side switching, each output can source up to 300mA. The input is non-inverting with a 1:1 ratio, controlled via an ON/OFF interface. The operating temperature range is -40°C to 125°C (TA). This component is suitable for applications requiring efficient driving of bipolar loads, such as in automotive systems, industrial automation, and motor control. The 16-PowerSOIC package (0.295", 7.50mm Width) is provided on tape and reel.
