The DA29020 is a 5-channel driver for external high-side switches with integrated charge-pump. It is intended for PWM operation controlled by an external uC.
The SPI interface provides a variety of configuration options to optimize EMC performance.
The built in 10-Bit ADC allows for measurements of channel currents, various interface voltages and the die temperature.
The integrated programmable short-circuit protection, over- and under- voltage detection and overtemperature shut-down protect the chip and the load.
Operation in harsh environments including ground-shift, ground-loss, strong supply-transients, polarity reversal and a wiring-harness with significant inductance is supported.
A programmable high-voltage control-input and a high-voltage diagnosis-output provide connection to the environment.
Low-power sleep mode and different selectable wake-up mechanisms help to reduce the system-level power consumption.
