LTC1710

ABSOLUTE MAXIMUM RATINGS

(Voltages Referred to GND Pin) (Note 1)

Input Supply Voltage (VCC).......................... – 0.3V to 6V

Input Supply Voltage (VCC) with SW0 Connected

as a Low Side Switch ........................... – 0.3V to 3.6V

DATA, CLK (Bus Pins 6, 5)......................... – 0.3V to 6V*

AD1 ( Address Pin 3) ....................... – 0.3V to VCC + 0.3V

OUT0, OUT1 (Output Pins 2, 7) ................... – 0.3V to 6V

SW0D (Switch 0 Drain Pin 1)....................... – 0.3V to 6V

OUT0, OUT1 (Output Pins 2, 7)

Continuous .................................................... 300mA

Pulsed, < 10

µs (nonrepetitive) ............................... 1A

Operating Temperature Range

LTC1710C ................................................ 0

°C to 70°C

LTC1710I ............................................ – 40

°C to 85°C

Junction Temperature** ...................................... 125

°C

Storage Temperature Range .................. – 65

°C to 150°C

Lead Temperature (Soldering, 10 sec)................... 300

°C

*Supply rails to DATA and CLK are independent of VCC to LTC1710.

**Although the LTC1710 can sustain TJMAX = 125°C without damage, its internal protection

circuitry is set to shut down the switches at TJ = 120°C with 15°C hysteresis.
