L9959T Datasheet | STMicroelectronics

Features - Full path RDSON less than 540 m - Continuous load current > 3 A - Operating battery supply voltage 5 V to 28 V - Operating VDD supply voltage 4.5 V to 5.5 V - All ECU internal pins can withstand up to 18 V - Output switching frequency up to 11 k Hz - Monitoring of VDD supply voltage - SPI programmable output current limitation from 5 A to 8.6 A (in 3 steps) - Over temperature and short circuit protection - Full diagnosis capability - Fast switch-off open-drain input/output - Current-monitoring with current feedback output signal CF - SPI-interface for configuration and diagnosis - Error history in second diagnosis register - Two independent enable pins: "/ABE" and "DIS" - Control of power stages by SPI or two input signals, PWM and DIR (configurable via SPI) - Logic levels 5 V patible - Conformity to improved EMC requirements due to smart H-bridge switching Description L9959S and L9959T are a single and dual integrated H-bridges for resistive and inductive loads featuring output current direction and supervising functions. The Power SSO24 houses one full H-Bridge, while the Power SSO36 houses two H-Bridges that can work in parallel, through independent input driving mands. Target application ranges from throttle control actuators to exhaust gas recirculation control valves in automotive domain to a more general use to drive DC and Stepper motors.
