MPC17533 - Dual H-Bridge Motor Driver

Description

Output A of H-Bridge channel 1.

Motor Drive Power Supply 1 Positive power source connection for H-Bridge 1 (Motor Drive Power Supply).

Features

  • built-in shoot-through current protection and an undervoltage shutdown function. The 17533 has four operating modes: forward, reverse, brake, and tri-stated (high-impedance). The 17533 has a low total RDS(ON) of 1.2 Ω (max at 25 °C). The 17533’s low output resistance and high slew rate provides efficient drive for many types of micromotors. Features.
  • Low total RDS(ON) 0.8 Ω (typ), 1.2 Ω (max) at 25 °C.
  • Output current 0.7 A (DC), 1.4 A (peak).
  • Shoot-through current prot.

Freescale Semiconductor Technical Data Document Number: MPC17533 Rev. 3.0, 12/2013 0.7 A 6.8 V Dual H-Bridge Motor Driver 17533 The 17533 is a monolithic dual H-Bridge power IC ideal for portable electronic applications containing bipolar stepper motors and/or brush DC-motors (e.g., cameras and disk drive head positioners). The 17533 operates from 2.0 V to 6.8 V, with independent control of each H-Bridge via parallel MCU interface (3.0 V and 5.0 V compatible logic). The device features built-in shoot-through current protection and an undervoltage shutdown function. The 17533 has four operating modes: forward, reverse, brake, and tri-stated (high-impedance). The 17533 has a low total RDS(ON) of 1.2 Ω (max at 25 °C).
