36V, 3.5A Brushed Motor Driver with

Integrated Current Sense

MAX22201/MAX22202/

MAX22207

General Description

Benefits and Features

The MAX22201/MAX22202/MAX22207 integrate one

36V, 3.5A peak full bridge capable of driving one brushed

DC motor. The full bridge features very low impedance

sulting in high driving efficiency. The peak current rating

of 3.5A is limited by the overcurrent protection threshold

(OCP). The peak current is defined as the maximum cur-

rent the driver can provide for short transients. The maxi-

mum RMS current is 2A and is typically limited by thermal

JEDEC 4-layer board at 25°C ambient temperature. The

real operating maximum current depends on the appli-

cation thermal characteristic (PCB ground planes, heat

sinks, ventilation, etc.).

● Lossless Integrated Current Sensing (ICS) Eliminates

External Bulky Resistors and Saves Power

● Current Sense Output (CSO) Function: A Replica of

the Internally Sensed Current is Output on the ISEN

● Current Drive Regulation Monitor (CDROUT)

(MAX22207 only)

● Fault Indicator pin (FAULT)

The MAX22201/MAX22202/MAX22207 feature a non-dis-

sipative and accurate integrated current sensing (ICS) and

an embedded internal current drive regulation (CDR) cir-

cuit to monitor the current through a motor coil and limit

the peak output current. When the motor current exceeds

the current limit threshold, the full bridge enters a decay

applications, the current drive regulation guarantees safe

and reliable operation of the driver under normal condi-

tions or during motor startup and stall conditions, and al-

so reduces system power and supply bypassing require-

ments. A scaled copy of the internally sensed current is

output to an external pin (ISEN). For more information on

these features, refer to the Detailed Description.

● Ultra-Small Package TDFN12 3mm x 3mm

All versions feature overcurrent protection (OCP), thermal

shutdown (TSD), and undervoltage lockout (UVLO). An

open-drain active-low fault indication pin (FAULT) is acti-

vated every time a fault condition is detected.

The device is packaged into a tiny TDFN12 3mm x 3mm

package. The small package footprint, the extremely high

efficiency and the integrated accurate current sensing

make the MAX22201/MAX22202/MAX22207 an excellent

choice for space- and power-sensitive applications.

Applications

● Brushed DC Motor Drive

● Stepper Motor Drive (One Phase Only)

● Latched Valves and Solenoids
