High-Speed, Power MOSFET Compatible Efficient High Frequency Operation Cross-Conduction Current Spike Enable Shutdown Functions Wide Input Voltage Range Protection
DESCRIPTION
UC1708 family power drivers made with high-speed, high-voltage, Schottky process interface control functions high-power switching devices particularly power MOSFETs. Operating over supply range, these devices contain independent channels. inputs compatible with CMOS logic families, withstand input voltages high VIN. Each output source sink long power dissipation limits exceeded. Although each output activated independently with inputs, they forced common through action either digital high signal Shutdown terminal forcing Enable terminal low. Shutdown terminal will only force outputs low, will effect behavior rest device. Enable terminal effectively places device under-voltage lockout, reducing power consumption much 90%. During under-voltage disable (Enable terminal forced low) conditions, outputs held self-biasing, low-voltage, state. UC3708 UC2708 available plastic 8-pin MINI 16-pin bat-wing packages commercial operation over 70°C temperature range industrial temperature range -25°C 85°C respectively. operation over -55°C 125°C temperature range, UC1708 available hermetically sealed 8-pin MINI CDIP, CDIP CLCC packages. Surface mount devices also available. BLOCK DIAGRAM
