DESCRIPTION
•23 Three Half-H-Bridge Driver IC
– Drives 3-Phase Brushless DC Motors
– Individual Half-Bridge Control
– Pins for Low-Side Current Sensing
– Low MOSFET On-Resistance
• 2.5-A Maximum Drive Current at 24 V, 25°C
• Uncommitted Comparator Can Be Used for
Current Limit or Other Functions
• Built-In 3.3-V 10-mA LDO Regulator
The DRV8313 provides three individually controllable
half-H-bridge drivers. It is intended to drive a three-
phase brushless dc motor, though it can also be used
to drive solenoids or other loads. Each output driver
channel consists of N-channel power MOSFETs
configured in a half-H-bridge configuration. The
design brings the ground terminals of each driver to
pins, to allow one to perform current sensing on each
output.
Current-limit circuitry or other functions are possible
uses of an uncommitted comparator.
• 8-V to 60-V Operating Supply Voltage Range
• Thermally Enhanced Surface-Mount Package
APPLICATIONS
• HVAC Motors
• Consumer Products
• Office Automation Machines
• Factory Automation
The DRV8313 can supply up to 2.5-A peak or 1.75-A
rms output current per channel (with proper PCB
heatsinking at 24 V and 25°C) per half-H-bridge.
The device provides internal shutdown functions for
overcurrent protection, short-circuit protection,
undervoltage lockout, and overtemperature.
The DRV8313 comes in a 28-pin HTSSOP
PowerPAD™ package.
