General Description
The RE46C102 is a dual H-bridge driver with 35mA
drive current and 16V VBB maximum driver supply
voltage. A separate low-side driver ground
connection, Vss, is provided for current monitoring of
each H-bridge driver. Each driver has two control
inputs:
ENABLE which enables the high-side
drivers and therefore connects the driver
supply to the motor output. This input can be
used for pulse-width modulation.
PHASE which is used to reverse the motor
polarity.
All control inputs are CMOS and TTL compatible
and the logic section operates at Vdd=5V.
Features
• Typical Quiescent Current < 1uA
• Output Current of 35mA
• Output Voltage to 16V
• Internal Clamp Diodes
• Available in Standard Packaging or RoHS
compliant Pb free packaging

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are
stress ratings only and operation at these conditions for extended periods may affect device reliability.
This product utilizes CMOS technology with static protection; however proper ESD prevention procedures should be used
when handling this product. Damage can occur when exposed to extremely high static electrical charge
