MAX22208AUU‌ is a 65V, 3.8A four-way half-bridge driver with integrated current detection. It is suitable for driving solenes, brushed DC motors, stepper motors or a combination of different loads, featuring high performance and low heat consumption ‌.

Key features of MAX22208AUU include:

Four independent half H-bridge drives

Maximum operating voltage: 65V

0.3Ω (typical value) RON (high + low), TA = +25°C

Fully independent half-bridge control

Current rating for each H-bridge (TA = +25°C) :

IMAX = 3.8A (pulse current driving a small capacitance load)

IRMS = 2A

Integrated current detection (ICS) improves efficiency by eliminating the need for bulky external resistors

Current detection output monitor

FAULT indicator pin

Overcurrent protection (OCP) for each individual channel

Undervoltage lock (UVLO)

Thermal shutdown TSD = +155°C

4.4mm x 9.7mm, 38-pin TSSOP package

More details

The MAX22208AUU offers four independently controlled 65V, 3.8AMAX H half-bridge drivers. It can drive four solenids, two brushed DC motors, a stepper motor, or a combination of different loads.

The MAX22208AUU's power supply FETs have a very low impedance and, as a result, drive efficiency is high and heat dissipation is minimal. The typical value of total RON (high + low end) is 0.3Ω (typical value). Each half-bridge can be individually controlled by pulse width modulation (PWM) using two logical inputs (DIN_, EN_).

The MAX22208AUU's integrated lossless current detection eliminates the need for larger external power resistors, resulting in significant space and power savings compared to mainstream applications based on external detection resistors.

The MAX22208AUU features overcurrent protection (OCP), thermal shutdown (TSD), and undervoltage lock (UVLO) protection. An open leak low-level active FAULT pin is activated each time a fault condition is detected.

Application scenario

The MAX22208AUU is widely used in half-bridge drive scenarios that require independent control, including:

Dc brush motor driver

Stepper motor driver

Solenoid valve driver

Latch valve
