MIC841/842

Comparator with 1.25% Reference and

Adjustable Hysteresis

General Description

Features

The MIC841 and MIC842 are micro-power, precision-

voltage comparators with an on-chip voltage reference.

• 1.5V to 5.5V operating range

• 1.5μA typical supply current

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.

• ±1.25% voltage threshold accuracy

• 10nA maximum input leakage current overtemperature

• 10µs propagation delay

• Externally adjustable hysteresis (MIC841)

• Internal 20mV 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

• Immune to brief input transients

• Teeny 5-pin SC-70 package

• 6-pin 1.6mm × 1.6mm TDFN (MIC841)

• 4-pin 1.2mm × 1.6mm TDFN (MIC842)

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.

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

ideal for portable applications.

Applications

• Smart phones

• PDAs

• Precision battery monitoring

• Battery chargers

The MIC841/2 is supplied in Micrel’s Teeny™ 5-pin

SC-70, 6-pin 1.6mm × 1.6mm Thin DFN (MIC841), and 4-

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