Description
www.DataSheet.net/
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. The integrated SPI
controls all operating modes (forward, reverse,
brake and high impedance). Also all diagnostic
information is available via SPI read.
