The TMI8263R provides an integrated motor driver solution for printers, scanners, an🐈d other automated equipment apℱplications. 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 interfacing𓆉 to controꦐller circuits. The TMI8263R is capa🧜ble 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.&😼nbsp;
Internal protection featu💎res are provided for over current, undervoltage and over tempe෴rature. Fault conditions are indicated on nFAULT.
The TMI8263R which comply with ROHS specifications, and the lead frame is 100% lead-free.
