Overview

Introducing our family of multi-channel, SPI-controlled Smart Actuator Drivers, including high-side, half-bridge, and BLDC (B6) bridge FET pre-drivers. These solutions are designed to support 12 V, 24 V, and 48 V systems across a wide operating voltage range. Featuring a 32-bit SPI interface for configuration, fault, and status readouts, the smart actuator drivers are built to reduce MCU overhead and enable streamlined platform development. Each device supports configurable load drive profiles for capacitive and motor loads. Precision current sensing is achieved via internal shunt resistors or external low-cost shunts, with integrated ADCs providing digital readout over SPI.

Built-in protection and diagnostics include integrated wire protection (12 V), EEPROM, configurable overcurrent protection, reverse battery, UV lockout, thermal shutdown, open load, and short-to-battery detection. Additional features include an internal PWM generator, Limp Home Mode, low shutdown current, and an ambient temperature range of –40 °C to 125 °C. All devices are available in leadless packages.
