R&E International A Subsidiary of Microchip Technology Inc. RE46C102 CMOS Dual H-Bridge Driver Product Specification General Description Features 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. 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 Pin Configuration 16 Lead Plastic DIP VBB 1 16 VDD ENABLEA ENABLEB PHASEA PHASEB GND GND GND GND OUT1A OUT1B OUT2A OUT2B VSSA VSSB Absolute maximum ratings Supply Voltage Vdd ......................................................-.5V to +17V Output Supply Voltage Vbb...........................................

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 (c) 2009 Microchip Technology Inc.
