LT1089CT

The LT1089CT is a logic driven, high current, high side switch utilizing bipolar technology. The device is capable of driving loads up to 7.5A with a low series drop of only 1.5V, and the series drop is specified over the full range of switch currents. The device has internal current limiting and thermal overload protection. The input logic is designed so that the output can drive loads referenced either above or below the device ground pin. Either positive or negative logic can be used to drive the input. The device is available in both TO-3 metal can and TO-220 plastic packages.

Features of the LT1089CT are:(1)7.5A switch capability; (2)low series drop (< 1.5V at 7.5A); (3)logic input (positive or negative logic); (4)current limited; (5)thermal overload; (6)5mA quiescent current; (7)10s risetime.

The absolute maximum ratings of the LT1089CT can be summarized as:(1)switch voltage (VCC VOUT):30V; (2)logic input voltage (VIN GND):15V; (3)logic input voltage range (VlN):(VCC 30V) < VIN < VCC; (4)ground pin voltage range (GND):(VCC 30V) < GND < VCC; (5)operating junction temperature range LT1089M grades:55°C to 150°C; (6)operating junction temperature range LT1089C grades:0°C to 125°C; (7)storage temperature range : 65°C to 150°C; (8)lead temperature (soldering, 10 sec):300°C.
