Abstract:
1. A power MOSFET driver comprising: a semiconductor package having no more than eight external connection terminals and containing a semiconductor die on which the power MOSFET driver is formed; a first input of the no more than eight external connection terminals configured to receive a supply voltage having a first value for powering the power MOSFET driver, wherein the power MOSFET driver externally receives the supply voltage; a first transistor driver coupled to operate from the supply voltage and form a first drive signal operable to drive a first MOS transistor; a circuit configured to form a first power supply voltage having a second value that is less than the first value of the supply voltage and is derived internally within the power MOSFET driver from the supply voltage; control logic configured to operate from the first power supply voltage; and a second transistor driver coupled to operate from a second power supply voltage having a third value that is less than the second value and form a second drive signal operable to drive a second MOS transistor.
