产品详情和应用
The MAX25616 is a highly integrated IC that includes a high-current VCSEL/IR driver, high-voltage DC-DC step-down converter, and I2C digital interface, providing a compact solution for automotive driver monitoring systems.
The high-current VCSEL/IR driver features an Analog Devices-proprietary driver that is designed to operate from 4V to 36V and provide peak currents up to 10A. The output voltage of the step-down converter is set at 3.3V (factory-adjustable from 2.8V to 5.2V in 50mV increments) and can provide up to 3A current.
The device features an I2C serial interface for communication with an external microcontroller. The I2C interface programming options include: VCSEL/IR current, VCSEL/IR maximum on-time, and switching frequency of the VCSEL/IR driver. Additionally, the device provides fault and diagnostic information through the I2C interface. An integrated 8-bit ADC converts the VCSEL/IR voltage and VCSEL/IR instantaneous current. By connecting a resistor-divider with an NTC to the AIN1/AIN2 input, the VCSEL/IR temperature can be sensed and read through the I2C interface.
The device is available in a 28-pin, 5mm x 5mm FC2QFN package and is specified for -40°C to +125°C operation.
