ELM77xxxxxC _{CMOS Dual voltage detector}

■General description

ELM77xxxxxC is CMOS dual voltage detector which consists of two comparator circuits watching Vdetn2

(Vdd level) and Vdetn1(Vdet input level) simultaneously and independently. This conﬁguration enables output

to maintain the state of detection even when voltage of the Vdet input level drops to 0V.

■Features

■Application

• Detection voltage range

: Vdetn1 (Vdet) 0.8V to 5.0V (by0.1V)

Vdetn2 (Vdd) 1.1V to 5.0V (by0.1V)

• Reset for microcomputers

• Power voltage shortage detectors

• Switch of backup power source

• Battery checkers

• Low current consumption : Typ.0.6μA(Vdd=3.0V)

• High accuracy of

detection voltage

: ±2.0%(Vdetn1,2>1.5V)

±30mV(Vdetn1,2≤1.5V)

: Typ.10MΩ

• High input resistance

• Low temperature coefficient : Typ.±100ppm/°C

• Output configuration

• Small package

: N-ch open-drain

: SOT-25
