L99DZ81EP 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.
L99DZ81EP 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 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 consumption in standby mode (IS < 6 µA typ; Tj 85°C)
- Current monitor output for all high-side drivers
- Central two-stage charge pump
- Motor bridge driver with full Rdson down to 6 V
- Device contains temperature warning and
