NJW4305A

NJW4305A 3 PHASE BRUSHLESS DC MOTOR CONTROLL IC ■ GENERAL DESCRIPTION The NJW4305A is a 3 phase brush less DC motor controller IC. It uses hall element signal inputs and generates motor driving waveform. Output pre-driver is optimized to work with external Power MOS transistor for better power handling. Using the NJW4305A, 3-phase DC motor application with speed control feature can be easily achieved ■ PACKAGE OUTLINE NJW4305AVC3 (SSOP20-C3) ■ FEATURES ● Maximum Supply Voltage : 40V ● Operating Voltage Range : 7.3V to 36V ● Operating Ambient Temperature : - 40ºC to + 105ºC ● Quiescent Current : 3.2mA ( typ. ) at VCC=24V ● FG Output ● Lock Protection Function (Auto Release) ● Forward / Reverse Function ● Over Current Detection Function ● Thermal Shutdown Function ● UVLO Protection Circuit ● Direct PWM Control : up to 150kHz ● Bi-CDMOS Technology ● Package Outline : SSOP20-C3 Ver.2014-03-06 -1- NJW4305A ■ BLOCK DIAGRAM FG VCC...
