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.

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
