A4986 |
Part Number | A4986 |
Manufacturer | Allegro MicroSystems |
Description | The A4986 is a dual DMOS full-bridge stepper motor driver with parallel input communication and overcurrent protection. Each full-bridge output is rated up to 35 V and ±2 A. The A4986 includes fixed off-time pulse width modulation (PWM) current regulators, along with 2-bit nonlinear DACs (digital-to-analog converters) that allow stepper motors to be controll. |
Features | ▪ Low RDS(ON) outputs ▪ Internal mixed current decay mode ▪ Synchronous rectification for low power dissipation ▪ Internal UVLO ▪ Crossover-current protection ▪ 3.3 and 5 V compatible logic supply ▪ Thin profile QFN and TSSOP packages ▪ Thermal shutdown circuitry ▪ Short-to-ground protection ▪ Shorted load protection ▪ Low current Sleep mode, < 10 µA PACKAGES: 24-contact QFN 4 mm × 4 mm × 0.75 mm (ES package) Approximate footprint 24-pin TSSOP with exposed thermal pad (LP Package) DESCRIPTION The A4986 is a dual DMOS full-bridge stepper motor driver with parallel input communication and o. |
