H-bridge brushed DC motor driver controls DC and servo motor loads with SPI-programmable configuration and diagnostics. The driver operates from a 5 V to 28 V load supply and supports 10 A operation with 40 V transient capability. SPI selects slew-rate and current-limit settings, while 3.3 V and 5 V logic compatibility supports common microcontroller interfaces. Integrated low-RDS(on) N-channel MOSFETs, current feedback, and thermal current-limit behavior support inductive-load motor-control applications across a -40 °C to 125 °C ambient range.
