A3995 - DMOS Dual Full Bridge PWM Motor Driver

Description

The A3995 is designed to drive two DC motors at currents up to 2.4 A.

Capable of drive voltages up to 36 V, theA3995 includes two independent fixed off-time PWM current regulators that operate in either fast or slow decay mode, as determined by the MODE input.

Features

  • 36 V output rating.
  • 2.4 A, DC motor driver.
  • Synchronous rectification.
  • Internal undervoltage lockout (UVLO).
  • Thermal shutdown circuitry.
  • Crossover-current protection.
  • Very thin profile QFN package.

A3995 DMOS Dual Full Bridge PWM Motor Driver FEATURES AND BENEFITS ▪ 36 V output rating ▪ 2.4 A, DC motor driver ▪ Synchronous rectification ▪ Internal undervoltage lockout (UVLO) ▪ Thermal shutdown circuitry ▪ Crossover-current protection ▪ Very thin profile QFN package PACKAGE: 36-pin QFN 0.90 mm nominal height (suffix EV) Not to scale DESCRIPTION The A3995 is designed to drive two DC motors at currents up to 2.4 A. Capable of drive voltages up to 36 V, theA3995 includes two independent fixed off-time PWM current regulators that operate in either fast or slow decay mode, as determined by the MODE input. Internal synchronous rectification control circuitry is provided to improve power dissipation during PWM operation.
