Applications
■ Door actuator driver with 6 bridges for double
door lock control, mirror fold and mirror axis
control, highside driver for mirror defroster,
bulbs and LEDs (replacement for L9950).
Control block with external MOS transistor for
charging / discharging of electrochromic glass.
Descriptionwww.DataSheet.net/
The L99DZ70XP is a microcontroller driven
multifunctional door actuator driver for automotive
applications. Up to five DC motors and five
grounded resistive loads can be driven with six
half bridges and five highside drivers. An
electrochromic mirror glass can be controlled
using the integrated SPI-driven module in
conjunction with an external MOS transistor. The
integrated SPI controls all operating modes
(forward, reverse, brake and high impedance).
Also all diagnostic information is available via SPI
read.
