描述 Description

The TMI8876 is a motor driver for wide variety of end applications. The device integrates an H-bridge, charge pump regulator, current sensing and regulation, current proportional output, and protection circuitry. The charge pump improves efficiency by allowing for both high and low side N-channels MOSFETs and 100% duty cycle support. Integrated current sensing allows for the driver to regulate the motor current during start up and high load events. A current limit can be set with an adjustable external voltage reference.Additionally, the device provides an output current proportional to the motor load current. This can be used to detect motor stall or change in load conditions. A low-power sleep mode is provided to achieve ultra- low quiescent current draw by shutting down most of the internal circuitry. The device is fully protected from faults and short circuits, including undervoltage lockout (UVLO), output over-current protection (OCP), and device thermal shutdown (TSD). Fault conditions are indicated on nFAULT.
