NJW4371E3
( SOP24-E3 )
DUAL H BRIDGE DRIVER
GENERAL DESCRIPTION PACKAGE OUTLINE
The NJW4371 is a general purpose dua l H Bridge driver IC.
It consists of a pair of Nch DMOS H bridges, gate driving
charge pump circuit, therma l shut down and UVLO circuit.
Each H bridge can individually be controlled with TTL/CMOS
compatible signal. Therefore, it is applicable for a wide range of
applications such as driving a two phase stepping motor, two
DC brushless motors, solenoids, lamps and other high voltage
switching needs using micr o controller .
FEATURES
• Wide Voltage Range VMM=10 to 27V
• Low ON Re sistance RON=1.65Ω typ.@Io=±1000mA
• Low Quiescent Current IMM=10mA typ.
• PWM Control A vailable
• Under V oltage Lock Ou t (UVLO)
• Thermal Shutdown Circuit
• BCD Process Technology
• Package Outline SOP24-E3 JEDEC 300mil
