XC612_1 Datasheet, PDF (12/14 Pages) Torex Semiconductor – 2-Channel Voltage Detectors

XC612 Series
■APPLICATION CIRCUITS EXAMPLE *Example covers N-channel open drain product's circuits
●Window comparator circuit
●Detect voltages above respective established voltages circuit
On resistors R1 and R2 equation (1) and (2)
Detect voltage = { (R1 + R2) ÷ R2} × VDF2
N.B. VDF2 = detect voltage VD2
Hysteresis (VHYS2) = { (R1 + R2) ÷R2 } × VHYS2
(1)
(2)
Note: Please ensure that input voltage 2 (VIN2) is less than VIN1 + 0.3V
●Detect voltage circuit with delay built-in
12/14
Note: Delay operates at both times of release and
detect operations.
