II Input current RESIN VI = 0.4 V to VCC –10 µA
SENSE, TL7702B VI = VREF to 18 V –0.1 –2
IOH High-level output current, RESET VO = 18 V, see Figure 7-1 50 µA

(1) All electrical characteristics are measured with 0.1-µF capacitors connected at REF, CT, and VCC to GND.
(2) Full range is 0°C to 70°C for the C-suffix devices, –40°C to 85°C for the I-suffix devices, and –40°C to 125°C for the Q-suffix device.
(3) This is the lowest voltage at which RESET becomes active.
