General Description

The MAX22910 is an industrial high-side switch that

operates as a current sourcing output device. The highside

switch has an on-resistance RON of 21mΩ (typ) and

40mΩ (max). The maximum load current is limited and

set via the CURLIM resistor in the range of 0.7A to 9A

with ±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 levels

in the range of 1.6V to 5.5V.

Open-wire detection detects wiring faults when the

switch is on for load current below a threshold in the

range of 1mA to 7mA, as set by the WBSET resistor.

Accurate load current monitoring at the IMON current

output monitors the load current with ±4 accuracy

between 2A and 9A and with ±6 accuracy between

0.7A and 2A when the device is not in the current limit.

The MAX22910 is protected against short-circuits,

overcurrent, and thermal overload. Achieve fast load

turn-off time by connecting an external TVS diode at

OUT with a high clamp voltage to clamp inductive

kickback energy.

The MAX22910 is available in a compact 4.5mm x

5.75mm FC2QFN package and is specified for operation

from -40°C to +125°C ambient temperature.
