MIC841 Pin Description

Pin Number

SC-70

Pin Number

TDFN

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 VLTH < 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.

VDD

Power Supply Input

−

No Connect. Not internally connected

−

ePad

Heatsink Pad. Connect to GND for best thermal performance.
