General Description

The L99DZ81EP is a microcontroller driven multifunctional door actuator driver for automotive applications.

Up to two DC motors and four grounded resistive loads can be driven with three half bridges and four high-side drivers.

Four external MOS transistors in bridge configuration can be driven.

Key Features

  • One full bridge for 6 A load (RON = 150 m).
  • One half bridges for 3 A load (RON = 300 m).
  • One configurable high-side driver for up to 1.5 A (RON = 500 m) or 0.35 A (RON = 1600 m) load.
  • One configurable high-side driver for 0.7 A (RON = 800 m) or 0.35 A (RON = 1600 m) load.
  • Two high-side drivers for 0.5 A load (RON = 1600 m).
  • Programmable softstart function to drive loads with higher inrush currents as current limitation value.
  • Very low VS current consump.
