BUK204-50X is a high side switch produced by Philips Semiconductors. It adopts 5V logic compatible input, has low on-state resistance, over temperature protection, overload protection, high voltage load protection, low static current, reverse battery and overvoltage protection and other features.
The Philips BUK204-50X is a monolithic temperature and overload protected power switch based on MOSFET technology, available in a 5-pin plastic surface mount envelope. It is configured as a single high side switch designed for general controller applications to drive lamps, motors, solenoids, and heaters.
Key features include low on-state resistance, 5 V logic compatible input with hysteresis, overtemperature protection that self-resets with hysteresis, and overload protection against short circuit loads with output current limiting. The device also provides status indication for overload and open circuit loads, along with very low quiescent current and voltage clamping for the turn-off of inductive loads.
