SC-70-5 (C5)

Pin Description MIC841

Pin Number

Pin Name

Pin Function

HTH

High Threshold Input. HTH and LTH monitor external voltages.

GND

Ground.

LTH

Low Threshold Input. LTH and HTH monitor external voltages.

OUT

(“H” Version) Active-Low Push-Pull Output. OUT asserts low when VLTH <

VREF. OUT remains low until VHTH > VREF.

OUT

(“L” Version) Active-High Push-Pull output. OUT asserts high when VLTL <

VREF. OUT remains high until VHTH > VREF.

OUT

(“N” Version) Active-Low, Open-Drain Output. OUT asserts low when VLTH <

VREF. OUT remains low until VHTH > VREF.
