- TMI8130A: ETSSOP24
The TMI8130A 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 sensi𝕴ng allows 𒆙for the driver to regulate the motor current during start up&nꦺbsp;and high ♛load events. A cu𒈔rrent limit can be set with an adjustable external voltage reference💫. Additionally, the device provides an output current proportional to the motor load curr🐼ent. 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 curr൲ent draw by shutting down most of the internal c🅷ircuitry. The device is fully protected from faults and ܫ;short circu𓆏its, including undervoltage lockout (UVLO), output over-current prote🐲𒉰ction (OCP), and device thermal shutdown (TSD). Fault conditions are indicated on nFAULT.
