Product Description

The DRV8818PWP is a 2.5A bipolar Stepper Motor Driver with on-chip 1/8 microstepping indexer. This device has two H-bridge drivers, as well as microstepping indexer logic to control a stepper motor. The output driver block for each consists of N-channel power MOSFETs configured as full H-bridges to drive the motor windings. A simple STEP/DIRECTION interface allows easy interfacing to controller circuits. The mode pins allow for configuration of the motor in full-step, half-step, quarter-step or eighth-step modes. Decay mode and PWM off time are programmable. Internal shutdown functions are provided for over-current protection, short-circuit protection, under-voltage lockout and over-temperature.
Pulse width modulation (PWM) microstepping motor driver
Built-In Microstepping Indexer
Over-current Protection (OCP) protection
Thermal shutdown (TSD) protection
VM under-voltage lockout (UVLO) protection
Fault condition indication pin (nFAULT) protection
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.
