ELECTRICAL CHARACTERISTICS

OUT: Open-Collector Output of Comparator. This pin

provides drive for up to 40mA of load current. Off-state

voltage may be as high as 18V (36V for LT6703HV) above

GND: Ground. This pin is also the low side return of the

internal 400mV reference.

IN: External Input for Comparator. The voltage on this

pin can range from –0.3V to 18V (36V for LT6703HV)

noninverting for the LT6703-3/LT6703HV-3, and inverting

for the LT6703-2/LT6703HV-2. The other comparator input

is internally connected to the 400mV reference.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: A heat sink may be required to keep the junction temperature

below the absolute maximum rating when the output is shorted

indefinitely.

Note 3: The inputs are protected by ESD diodes to the ground pin. If the

input voltage exceeds –0.3V below ground, the input current should be

limited to less than 10mA.

Note 4: The LT6703C-2/-3/LT6703HVC-2/-3, and LT6703I-2/-3/LT6703HVI-

2/-3 are guaranteed functional over the operating temperature range of

–40°C to 85°C.

The LT6703H-2/-3/LT6703HVH-2/-3, is guaranteed functional over the

operating temperature range of –40°C to 125°C.

Note 5: The LT6703C-2/-3/LT6703HVC-2/-3, are guaranteed to meet the

specified performance from 0°C to 70°C. The LT6703C-2/-3/LT6703HVC-

2/-3 are designed, characterized and expected to meet specified

performance from –40°C to 85°C but are not tested or QA sampled at

these temperatures. The LT6703I-2/-3/LT6703HVI-2/-3, are guaranteed

to meet specified performance from –40°C to 85°C. The LT6703H-2/-

3/LT6703HVH-2/-3, is guaranteed to meet specified performance from

–40°C to 125°C.
