Circuit device of e.g. lamp, has MOSFET which is actuated by pulse width modulation (PWM) signal and NTC resistor which is established to influence rising and falling edges of PWM signal

摘要

The circuit device (2) has a negative temperature coefficient (NTC) resistor (10) that is coupled with a MOSFET (4), through a coupling portion (14). The MOSFET is actuated by pulse width modulation (PWM) signal (8). The NTC resistor is established to influence the rising and falling edges of the PWM signal. An independent claim is included for method for operation of MOSFET using pulse width modulated signal.
