TMI8263R Dual H-Bridge Motor Driver

PublishTime： 2023-12-25 Manufacturer： TOLL Type： Datasheet Language： English

●GENERAL DESCRIPTION
■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.
