PT12493 - 8-Channels SPI Controlled Half-Bridge Driver

General Description

The PT12493 is an integrated multi-channel halfbridge drivers with 8 half-bridges.

Key Features

  • low on- state resistance (RDS(ON)) for improved thermal performance during high-current operation. This device can drive brushed-DC (BDC) motors or stepper motors in independent, sequential, or parallel mode. The half-bridges are fully controllable to achieve a forward, reverse, coasting and braking operation of motor. This device feature standard 16-bit, 5-MHz serial peripheral interface (SPI) with daisy chain capability for complete configuration and detailed diagnostics. The device has eight.
