MAX22207ATC+

MAX22207 is a 36V, 3.5A brushed motor driver with integrated current sense. The full bridge features very low impedance FETs with a typical RON (high side + low side) of 0.3 ohm resulting 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 current the driver can provide for short transients. The maximum RMS current is 2A and is typically limited by thermal considerations. The 2ARMS capability refers to a standard JEDEC 4-layer board at 25°C ambient temperature. The real operating maximum current depends on the application thermal characteristic (PCB ground planes, heat sinks, ventilation, etc.). It is used in applications such as brushed DC motor drive, stepper motor drive (one phase only), latched valves and solenoids.

• Configurable current drive regulation (CDR) for limiting stall and inrush current
• Supply-voltage range from 3V to 36V, current drive regulation monitor (CDROUT)
• Disable current consumption is 3.5μA typical at (TA = +25°C)
• Fault indicator pin (FAULT), fully integrated charge pump
• Overcurrent protection for each individual channel (OCP)
• Undervoltage lockout (UVLO), thermal shutdown (TSD) T = +165°C
• ESD protection 8kV HBM (OUT1 and OUT2 pins)
• Current sense output -3dB small signal bandwidth is 1MHz typical
• Minimum tON time is 2.5μs typical at (TA = +25°C)
• Operating temperature is -40°C to +125°C, package style is 12-lead TDFN
