The TMI8263R provides an integrated motor driver solution for printers, scanners, and other automated equipment applications. The device has two H-bridge drivers, and can drive a bipolar stepper motor or two brushed DC motors. The output driver block consists of N-channel power MOSFETs configured as H-bridges .
A simple PWM interface allows easy interfacing to controller circuits. The TMI8263R is capable of driving up to 2.8-A peak output current per H-bridge. A low-power sleep mode is provided to achieve ultra- low quiescent current draw by shutting down most of the internal circuitry.
Internal protection features are provided for over current, undervoltage and over temperature. Fault conditions are indicated on nFAULT.
The TMI8263R which comply with ROHS specifications, and the lead frame is 100% lead-free.
