- TMI8130: ETSSOP24
The TMI8130 is a motor driver for wide variety&nbs꧃p;of end appliওcaꦕtions. The device integrates an H-bridge,charge pump regulator,current sensing and regulation, current proportional&n♉bsp;output, and protec🏅tion circuitry. The charge pump impr🌠oves efficiency by allowing f💯or both high and low side N-channels MOSFETs and 100% duty cycle support.
Integraಌted current sensing allows for the driver ಞto regulate the motor current during꧑ start up and hig൩h load events. A current limit can be s🎉et wꦡith an adjustable external voltage reference. Additionally, the device provides an output current proportiona𒆙l 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 circu𓄧itry. The device is fully protected from faults and&🔯nbsp;short circuits, including undervoltage lockout🐻 (UVLO), output over-current protection (ꦇOCP), and device thermal shutdown (TSD). Fault conditions are indicated on nFAULT.
