ADP3624

www.DataSheet4U.com High Speed, Dual, 4 A MOSFET Driver with Thermal Protection ADP3624/ADP3634 GENERAL DESCRIPTION The ADP3624/ADP3634 are high current drive, dual high speed drivers, capable of driving two independent N-channel power MOSFETs. The part uses the industry-standard footprint but adds high speed switching performance and improved system reliability. The part has an internal temperature sensor and provides two levels of overtemperature protection, an overtemperature warning and an overtemperature shutdown at extreme junction temperatures. The SD function, generated from a precise internal comparator, provides fast system enable or shutdown. This feature allows redundant overvoltage protection, complementing the protection inside the main controller device, or provides safe system shutdown in the event of an overtemperature warning. Wide input voltage range allows the driver to be compatible with both analog and digital PWM controllers. Digital power controllers are supplied from a low voltage supply, and the driver is supplied from a higher voltage supply. The ADP3624/ADP3634 add UVLO and hysteresis functions, allowing safe startup and shutdown of the higher voltage supply when used with low voltage digital controllers. The device family is available in thermally enhanced SOIC_N_EP and MINI_SO_EP packaging to maximize high frequency and current switching in a small printed circuit board (PCB) area.
