Additional Details

The MAX22910 is an industrial high-side switch that operates as a current sourcing output device. The highside switch has an on-resistance R_ON 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 V_L 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.

Product Detail

The MAX22910 evaluation kit (EV kit) provides a proven design to evaluate the MAX22910, a 21mΩ single-channel high-side switch with advanced diagnostics for industrial applications. The EV kit is powered from an external power supply at V_DD, while the on-board LT3014 LDO generates a 3.3V for the logic input level of the MAX22910. The logic level can be set with an external power supply at V_L, alternatively. The EV kit is preinstalled with ADuM342E0, a four-channel digital isolator with default-low output. It provides digital isolation between the field and logic sides for logic control I/Os.

The MAX22910 EV kit comes with an output clamping diode installed to protect the device from negative kickback voltage during switching off the inductive loads. The EV kit is specified for EMC protection against surge and ESD transients, EFT, and RF conducted immunity.

The MAX22910 EV kit comes with MAX22910AFZ+ installed in a compact 4.5mm x 5.75mm FC2QFN package. The EV kit is specified for operation with up to +60V supply voltage at V_DD and from -40°C to +125°C operating temperature range.
