L99DZ70XP Door actuator driver Features One full bridge for 6 A load (R = 150 m) on Two half bridges for 3 A load (R = 300 m) on Two half bridges for 0.75 A load (R = 1600 m) on One highside driver for 6 A load (R =90m) on PowerSSO-36 Two configurable highside drivers for up to 1.5 A load (R =500 m) or 0.4 A on (R = 1800 m) on Applications Two highside drivers for 0.5 A load (R = 1600 m) Door actuator driver with 6 bridges for double on door lock control, mirror fold and mirror axis Programmable softstart function to drive loads control, highside driver for mirror defroster, with higher inrush currents as current limitation bulbs and LEDs (replacement for L9950). value Control block with external MOS transistor for Very low current consumption in standby mode charging / discharging of electrochromic glass. (I <6A typ T 85 C I < 5 A typ S j CC T 85 C) j Description Current monitor output for all highside drivers The L99DZ70XP is a microcontroller driven Device contains temperature warning and multifunctional door actuator driver for automotive protection applications. Up to five DC motors and five Openload detection for all outputs grounded resistive loads can be driven with six Over-current protection for all otputs half bridges and five highside drivers. An electrochromic mirror glass can be controlled Separated half bridges for door lock motor using the integrated SPI-driven module in PWM control of all outputs conjunction with an external MOS transistor. The Charge pump output for reverse polarity integrated SPI controls all operating modes protection (forward, reverse, brake and high impedance). Also all diagnostic information is available via SPI STM standard serial peripheral interface (ST- read. SPI 3.0) Control block for electrochromic element Table 1.
