L99DZ81EP Door actuator driver Datasheet - production data Applications Door actuator driver with 3 bridges for double door lock control, 4 high-side drivers for bulbs and LEDs control. * 3*&)7 H-bridge control for external power transistors TQFP-64 Description Features The L99DZ81EP is a microcontroller driven multifunctional door actuator driver for automotive One full bridge for 6 A load (R = 150 m ) ON applications. Up to two DC motors and four One half bridges for 3 A load (R = 300 m) ON grounded resistive loads can be driven with three One configurable high-side driver for up to half bridges and four high-side drivers. Four 1.5 A (R = 500 m ) or 0.35 A external MOS transistors in bridge configuration ON (R = 1600 m ) load can be driven. The integrated SPI controls all ON operating modes (forward, reverse, brake and One configurable high-side driver for 0.7 A high impedance). Also all diagnostic information (R =800 m ) or 0.35 A (R = 1600 m) ON ON is available via SPI read. load Two high-side drivers for 0.5 A load (R =1600m ) ON Programmable softstart function to drive loads with higher inrush currents as current limitation value Very low V current consumption in standby S mode (I < 6 A typ T 85C) S j Current monitor output for all high-side drivers Central two-stage charge pump Motor bridge driver with full R down to 6 V dson Device contains temperature warning and protection Open-load detection for all outputs Table 1.
