Documents Rapports de stage DESCRIPTION The UC1707 family of power drivers is made with a high speed Schottky process to interface between low level control functions and high power switching devices particularly power MOSFETs These devices contain two independent channels each of which can be activated by either a high or low input logic level signal Each output can source or sink up to 5A as long as power dissipation limits are not exceeded Although each output can be activated independently with its own inputs it can be forced low in common through the action either of a digital high sig nal at the Shutdown terminal or a differential low level analog signal The Shutdown command from either source can either be latching or not de pending on the status of the Latch Disable pin Supply voltage for both VIN and VC can independently range from 5V to 40V These devices are available in two watt plastic bat wing DIP for operation over a 0°C to 70°C temperature range and with reduced power in a her metically sealed cerdip for –55°C to +125°C operation Also available in surface mount DW Q L packages Line Package
Documents Rapports de stage General Description The MAX6501–MAX6504 low cost fully integrated tem perature switches assert a logic signal when their die temperature crosses a factory programmed threshold Operating from a 7V to 5V supply these devices feature two on chip temperature dependent voltage references and a comparator They are available with factory trimmed temperature trip thresholds from 45°C to +115°C in 10°C increments and are accurate to 5°C typ or ±6°C max These devices require no external components and typically consume A sup ply current Hysteresis is pin selectable at +2°C or +10°C The MAX6501 MAX6503 have an active low open drain output intended to interface with a microprocessor P reset input The MAX6502 MAX6504 have an active high push pull output intended to directly drive fan control logic The MAX6501 MAX6502 are offered with hot temperature thresholds +35°C to +115°C assert ing when the temperature is above the threshold The MAX6503 MAX6504 are offered with cold temperature thresholds 45°C to +15°C asserting when the tem perature is below the threshold The MAX6501–MAX6504 are offered in eight standard temperature versions contact the factory for pricing and availability of nonstandard temperature versions They are available in pin SOT23 and pin TO packages Debra Buchanan

Documents Rapports de stage General Description The MAX6511 MAX6512 MAX6513 are fully integrated remote temperature switches that use an external P N junction typically a diode connected transistor as the sensing element to measure the remote temperature These devices assert a logic signal when the tempera ture crosses a factory programmed threshold Available trip thresholds are from +45°C to +125°C in 10°C incre ments Accuracy is within ±3°C TA 5°C to +55°C or ±5°C TA 40°C to +85°C Hysteresis is pin selec table to 5°C or 10°C The MAX6511 has an active low CMOS output and the MAX6513 has an active high CMOS output The MAX6512 has an open drain output The output is asserted when the temperature exceeds the threshold value The active low open drain output is intended to interface with a microprocessor P reset or interrupt input The active high CMOS output can directly drive a power FET to control a cooling fan The MAX6511 MAX6512 MAX6513 operate from a 0V to 5V supply and typically consume A of supply current They are available in a small pin SOT23 package Time Accuracy
