The TMI8262 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 DC motors. The output driver block for each consists of N-channel power MOSFET’s configured as full H-bridges to drive the motor windings. The TMI8262 is capable of driving up to 1.6-A of output current.
A simple parallel digital control interface is compatible with industry-standard devices. Decay mode is programmable.
Internal shutdown functions are provided for over current protection, short circuit protection, under voltage lockout and overtemperature.
The TMI8262 and TMI8262Q which comply with ROHS specifications, and the lead frame is 100% lead-free.
