LTC1693-5 High Speed Single P-Channel MOSFET Driver FEATURES DESCRIPTIO n Single MOSFET Driver in MSOP Package The LTC 1693-5 drives power P-channel MOSFETs at n 1.5A Peak Output Current high speed. The 1.5A peak output current reduces switch- n 16ns Rise/Fall Times at V = 12V, C = 1nF ing losses in MOSFETs with high gate capacitance. CC L n Wide V Range: 4.5V to 13.2V CC The LTC1693-5 is a single driver with an output polarity n CMOS Compatible Input with Hysteresis select pin. The MOSFET driver offers V independent CC n Input Threshold Is Independent of V CC CMOS input thresholds with 1.2V of typical hysteresis. It n Driver Input Can Be Driven Above V CC can level-shift the input logic signal up or down to the rail- n Undervoltage Lockout to-rail V drive for the external MOSFET. CC n Thermal Shutdown The LTC1693-5 contains an undervoltage lockout circuit U and a thermal shutdown circuit that disables the external APPLICATIO S P-channel MOSFET gate drive if activated. n Power Supplies The LTC1693-5 comes in an 8-lead MSOP package. n High Side Drivers , LTC and LT are registered trademarks of Linear Technology Corporation. n Motor/Relay Control n Line Drivers n Battery Chargers TYPICAL APPLICATIO High Efficiency 1.5A Li-Ion Battery Charger V IN 5V TO 6V MBRS130LT3 POSITION CAPACITOR CLOSE TO LTC1732 1F 332 332 0.47F 0.082 22F 8 0.25W CERAMIC V CC 4.7 9 SENSE POSITION CAPACITOR LTC1732 8 CLOSE TO SENSE RESISTOR 3 3 7 1 7 CHRG DRV Si2305DS LTC1693-5CMS8 10 1 4 ACPR BAT MBRS130LT3 4 6 TIMER PROG 18.2k GND SEL 22F 5 2 V CDRH6D38-220NC CC 0.1F AVX 0603ZC104KAT1A SEL USE LOW TEMPERATURE + + 1-CELL COEFFICIENT CAPACITOR 100F Li-Ion BATTERY 1693-5 TA01 CHARGE RATE 1.5A (DEPENDING ON V AND BATTERY VOLTAGE) IN 1 U ULTC1693-5 ABSOLUTE MAXIMUM RATINGS PACKAGE/ORDER INFORMATION (Note 1) ORDER PART Supply Voltage (V ) .............................................. 14V TOP VIEW CC NUMBER IN 1 8 V Inputs (IN, PHASE) ................................... 0.3V to 14V CC NC 2 7 OUT LTC1693-5CMS8 Driver Output ................................. 0.3V to V + 0.3V 6 NC CC PHASE 3 GND 4 5 NC Junction Temperature.......................................... 150 C MS8 PACKAGE Operating Temperature Range ..................... 0 C to 70 C MS8 PART 8-LEAD PLASTIC MSOP Storage Temperature Range ................. 65 C to 150 C MARKING T = 150 C, q = 200 C/ W JMAX JA Lead Temperature (Soldering, 10 sec).................. 300 C LTSG Consult factory for parts specified with wider operating temperature ranges.
