1.5 A load (R_on = 500 mΩ) or 0.4 A
(R_on = 1800 mΩ)
■ Two highside drivers for 0.5 A load
(R_on = 1600 mΩ)
■ Programmable softstart function to drive loads
with higher inrush currents as current limitation
value
■ Very low current consumption in standby mode
(I_S < 6 µA typ; T_j ≤ 85 °C; I_CC < 5 µA typ;
T_j ≤ 85 °C)
■ Current monitor output for all highside drivers
■ Device contains temperature warning and
protection
■ Openload detection for all outputs
■ Over-current protection for all otputs
■ Separated half bridges for door lock motor
■ PWM control of all outputs
■ Charge pump output for reverse polarity
protection
■ STM standard serial peripheral interface (ST-
SPI 3.0)
■ Control block for electrochromic element
PowerSSO-36
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.
Description
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.
