The MAX22204AUU is a two-phase stepper motor driver. It integrates two 65V, 3.8AMAX H Bridges. The impedance of the H-bridge FETs is very low, resulting in high drive efficiency and little heat dissipation. The typical value of total RON (high side + low side) is 0.3Ω. The MAX22204AUU integrates a precision current drive regulation circuit and a 128-microstep built-in divider controlled by the STEP/DIR interface. High microstep resolution and advanced control technology ensure smooth and quiet operation.
The MAX22204AUU has the following features:
The voltage rating of the two H Bridges is +65V
Total Rdson (high side + low side) : 300mΩ (typical) (TA = 25°C)
Current rating for each H-bridge (typical for TA = 25°C) :
IMAX = 3.8AMAX (Pulse current driving capacitive load)
IFS(MAX) = 2.8A (maximum full scale current setting for internal current drive regulation)
IRMS = 2ARMS/ phase (TA = 25°C, VM = +24V)
Integrated current control
Full scale DAC current can be configured using external resistors
The torque can be quickly changed between the two levels with a single logic input (TRQ)
Improves efficiency by providing internal current detection (ICS) without the need for larger external resistors
Built-in control via 128 microstep divider
STEP/DIR interface
Integrate DAC and timing controller for microstep function
Multiple attenuation modes (slow, mixed, adaptive)
An external resistor configuration can be used to fix the shutdown time
Current detection output (ISENA, ISENB) Current monitor
Active low level FAULT indicator pin
Protection function
Overcurrent protection for each channel (OCP)
Undervoltage Protection (UVLO)
Thermal shutdown TJ = 155°C (TSD)
