AUK S7129F

S71xxF
7
Semiconductor
Standard Voltage Detector
Description
• The S71xx prevents the error of system from supply voltage below normal voltage level at the time the power on
and instantaneous power off in systems.
Features
• Current Consumption is Low (ICCL=300 ㎂ Typ. ICCH =30 ㎂ Typ.)
• Resetting Output Minimum Guarantee Voltage is Low (0.8V Typ.)
• Hysteresis Voltage is Provided (50 ㎷ Typ.)
Applications
• As Control Circuit of Battery-Backed Memory
• As Measure Against Erroneous Operations at Power On-Off
• As Resetting Function for the CPU-Mounted Equipment --- PC, Printer, VTR, Fax, C-TV etc.
• As Measure Against System Runaway at Instantaneous Break of Power Supply etc.
