MAX22910中文资料21mΩ, 80V High-Side Switch with Advanced Diagnostics and Load Current Monitoring数据手册ADI规格书

描述 Description

The MAX22910 is an industrial high-side switch thatoperates as a current sourcing output device. The highsideswitch has an on-resistance RON of 21mΩ (typ) and40mΩ (max). The maximum load current is limited andset via the CURLIM resistor in the range of 0.7A to 9Awith ±10% accuracy. At +100°C ambient temperature,the maximum continuous load current is up to 7A.

The MAX22910 is specified for operation up to 80V(max) supply voltage if OUT does not go below GND.The VL logic supply allows flexible logic interface levelsin the range of 1.6V to 5.5V.

Open-wire detection detects wiring faults when theswitch is on for load current below a threshold in therange of 1mA to 7mA, as set by the WBSET resistor.

Accurate load current monitoring at the IMON currentoutput monitors the load current with ±4% accuracybetween 2A and 9A and with ±6% accuracy between0.7A and 2A when the device is not in the current limit.

The MAX22910 is protected against short-circuits,overcurrent, and thermal overload. Achieve fast loadturn-off time by connecting an external TVS diode atOUT with a high clamp voltage to clamp inductivekickback energy.

The MAX22910 is available in a compact 4.5mm x5.75mm FC2QFN package and is specified for operationfrom -40°C to +125°C ambient temperature.
