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 20 kHz Monitoring of VDD supply voltage including bidirectional switch-off pin NABE Overtemperature and short-circuit protection Full diagnosis capability Output stage with SPI-adjustable current limitation 5-8.
6 A in 3 steps (two-point regulation) Fast switch-off open-drain input/output Current-monitoring with current feedback output signal CF Reliable full diagnostic capability Settable chip-address via bond-wire configuration on the silicon or E-Fuse SPI-interface for configuration and diagnosis Error history in diagnosis register Two independent enable pins: "NABE" and "DIS" Control of power stages by SPI or two input signals, PWM and DIR (configurable via SPI) Logic levels 5 V compatible Conformity to improved EMC requirements due to smart H-bridge switching Full ISO 26262 compliant, ASIL-B (D) systems ready Description L9969S/L9969U and L9969T are single and dual integrated H-bridges for resistive and inductive loads featuring output current direction and supervising functions.
The PowerSSO24 houses one full H-bridge, while the PowerSSO36 houses both two H-bridges that can work in parallel, through independent input driving commands.
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.
