  • Description:

    DESCRIPTION
    CKM431 is an integrated 12V-operationable 3-phase
    sensorless BLDC motor driver with advanced
    protections which include soft-start circuit, thermal
    shutdown, lock protection and output current limit.
    CKM431 is specially designed for sensorless motor
    and ideal for fan motor control requiring high power
    efficiency. And a direct PWM-control interface is built
    in to smooth the fan speed from low to high.
    Peripheral devices are limited to few so that it is not
    difficult to make the PCB layout tight and small.
    CKM431 uses a new multi-power BCD technology,
    requiring a single power supply of VDD = 5~12V,
    packed as TSSOP16 package and displaying
    excellent power efficiency, is a perfect solution for
    comprising a compact, low-cost sensorless BLDC
    motor system.

Introduction
FEATURES
Multi-power BCD technology
Direct-PWM of 20~50 KHz for fan speed control
Adjustable soft-start time by an external
capacitor
Adjustable Lock protection time by an external
capacitor
Thermal protection of shutdown/release at 150
C/120C
Over-current limit set by an external precision
resistor
FG output is offered, which gives the pulse signal
as the hall sensor system
