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
• Detection voltage range
• Low current consumption
• High accuracy of
detection voltage
: Vdetn1 (Vdet) 0.8V to 5.0V (by0.1V)
Vdetn2 (Vdd) 1.1V to 5.0V (by0.1V)
: Typ.0.6μA(Vdd=3.0V)
: ±2.0%(Vdetn1,2>1.5V)
±30mV(Vdetn1,2≤1.5V)
■Application
• Reset for microcomputers
• Power voltage shortage detectors
• Switch of backup power source
• Battery checkers
• High input resistance
: Typ.10MΩ
• Low temperature coefficient : Typ.±100ppm/°C
• Output configuration
• Small package
: N-ch open-drain
: SOT-25
