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

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 charges
