DRV8412DDW Datasheet PDF - TI

●The DRV8412DDW is a high-performance dual brushed DC or single bipolar Stepper Motor Driver with an advanced protection system. Because of the low RDS (ON) of the H-bridge MOSFETs and intelligent gate drive design, the efficiency of this motor driver can be up to 97%. This high efficiency enables the use of smaller power supplies and heat sinks and the devices are good candidates for energy-efficient applications. The DRV8412 requires two power supplies, one at 12V for GVDD and VDD and another up to 50V for PVDD. The motor driver can operate at up to 500kHz switching frequency while still maintaining precise control and high efficiency. This device also has an innovative protection system safeguarding the device against a wide range of fault conditions that could damage the system. This safeguard is short-circuit protection, over-current protection, under-voltage protection and two-stage thermal protection.

● Integrated self-protection includes under-voltage, over-temperature, overload and short-circuit

● Programmable cycle-by-cycle current limit protection

● Independent supply and ground pins for each half bridge

● Intelligent gate drive and cross conduction prevention

● No external snubber or Schottky diode is required

● Green product and no Sb/Br

●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
