MIC841/2

Comparator with 1.25% Reference and Adjustable Hysteresis

Features

General Description

• 1.5V to 5.5V Operating Range

• 1.5 μA Typical Supply Current

• ±1.25% Voltage Threshold Accuracy

The MIC841 and MIC842 are micro-power,

precision-voltage comparators with an on-chip voltage

reference.

Both devices are intended for voltage monitoring

applications. External resistors are used to set the

voltage monitor threshold. When the threshold is

crossed, the outputs switch polarity.

• 10 nA Maximum Input Leakage Current Over

Temperature

• 10 μs Propagation Delay

• Externally Adjustable Hysteresis (MIC841)

• Internal 20 mV Hysteresis (MIC842)

• Output Options:

The MIC842 incorporates a voltage reference and

comparator with fixed internal hysteresis; two external

resistors are used to set the switching threshold

voltage. The MIC841 provides a similar function with

user adjustable hysteresis; this part requires three

external resistors to set the upper and lower thresholds

(the difference between the threshold voltages being

the hysteresis voltage).

- Push-Pull, Active-High

- Push-Pull, Active-Low

- Open-Drain, Active-Low

• Open-Drain Output can be Pulled to 6V

Regardless of V_DD

Both the MIC841 and MIC842 are available with

push-pull or open-drain output stage. The push-pull

output stage is configured either active-high or

active-low; the open-drain output stage is only

configured active-low.

• Immune to Brief Input Transients

• Teeny 5-Pin SC-70 Package

• 6-Pin 1.6 mm x 1.6 mm TDFN (MIC841)

• 4-Pin 1.2 mm x 1.6 mm TDFN (MIC842)

Applications

• Smartphones

Supply current is extremely low (1.5 μA, typical),

making it ideal for portable applications.

• PDAs

The MIC841/2 is supplied in the Teeny 5-pin SC-70,

6-pin 1.6 mm × 1.6 mm Thin DFN (MIC841), and 4-pin

1.2 mm × 1.6 mm Thin DFN (MIC842) packages.

• Precision Battery Monitoring

• Battery Chargers
