A89500GEJTR-T

Overview

The A89500GEJTR-T is an automotive-grade half-bridge MOSFET gate driver manufactured by Allegro MicroSystems. Designed for robust performance in demanding environments, it operates within a supply voltage range of 8 V to 15 V and supports junction temperatures from -40 °C to +105 °C. The device features two independent drivers with propagation delays capped at 32 ns. It exhibits rise and fall times of 105 ns and 46 ns, respectively, while maintaining a low quiescent current of 3 mA. Packaged in a DFN-10 surface-mount format, the component integrates internal protection mechanisms suitable for high-reliability applications.
