1 / 46 page  February 2011 Doc ID 16082 Rev 5 1/46 1 L99MD02 Hexa half-bridge driver with SPI control for automotive applications Features ■ 6 half bridges ■ RON = typ.0.9 Ω (HS), 0.64 Ω (LS) at Tj =25 °C ■ Current limit of each output at minimum 0.8 A ■ Internal PWM generation ■ PWM mode option for all half bridges for hold current ■ Two current monitor outputs ■ SPI interface for data communication ■ Temperature warning ■ All outputs overtemperature protected ■ All outputs short circuit protected ■ VCC supply voltage 3.0 to 5.3 V ■ Very low current consumption in standby mode typ. 5 µA ■ VS operating range compliant: 6 – 18 V Applications ■ DC motor driver Intended to drive HVAC flaps Description The L99MD02 IC is a 6 x half bridge driver for automotive applications. The device is intended to drive DC-motors. It is possible to drive 3 DC-motors simultaneously or up to 5 DC-motors sequentially. The integrated 24 bit standard serial peripheral interface (SPI) controls all outputs and provides diagnostic information: normal operation, open-load in on-state, overcurrent, temperature warning and overtemperature.
