资 源 简 介
The DRV8840 provides an integrated motor driver soluTIon for printers, scanners, and other automatedequipment applicaTIons. The device has one H-bridge driver, and is intended to drive one DC motor. The outputdriver block for each consists of N-channel power MOSFET’s configured as full H-bridges to drive the motorwindings. The DRV8840 can supply up to 5-A peak or 3.5-A output current (with proper heatsinking at 24 V and25°C).A simple parallel digital control interface is compaTIble with industry-standard devices. Decay mode isprogrammable to allow braking or coasTIng of the motor when disabled.Internal shutdown functions are provided for over current protection, short circuit protection, under voltagelockout and overtemperature.TheDRV8840 is available in a 28-pin HTSSOP package with PowerPAD™ (Eco-friendly: RoHS & no Sb/Br).
