PHILIPS TOPFET high side switch BUK220-50Y SMD version of BUK219-50Y handbook
The Philips BUK220-50Y is a monolithic single channel high side protected power switch utilizing TOPFET2 technology, assembled in a 5-pin plastic surface mount package (SOT426). It is designed as a general controller for driving lamps, motors, solenoids, and heaters, featuring low on-state resistance and CMOS logic compatibility.
The device includes comprehensive protection features such as overtemperature protection, load current limiting, latched overload and short circuit protection, and overvoltage/undervoltage shutdown with hysteresis. It also offers diagnostic status indication, voltage clamping for inductive loads, and ESD protection on all pins.
