GENERAL DESCRIPTION
The NJM2626 is a 3-phase DC brush less motor control
It takes hall IC inputs and generates motor driving
Output pre-driver is optimized to work with external power
The NJM2626 can easily implement 3-phase DC motor
Operating Voltage
Pre-driver circuit
Current limit sense voltage (Current limit=0.5V±10%)
Internal Oscillator
Forward or Reverse direction
Internal Soft Start (External capacitor to Verr pin)
Internal ON/OFF Circuit (No-output is Verr pin to GND)
Bipolar Technology
Package Outline
Upper arm : (Iout=30mA TYP.)
Lower arm : (Iout=+30mA/-30mA TYP.)
(Frequency control for external capacitor)
