TMI8116-Q1 H-bridge Motor Driver with Integrated Current Sense and Regulation
■The TMI8116-Q1 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.
