Overview:

D8128   Voltage detection circuit
The function of the D8128 is to accurately reset the system in various cpus and other logic systems after detecting the power supply voltage during power on and instantaneous power off.
The D8128 adopts the package form of SOT-23-3L.

 

Main features:

● Low power consumption: ICCL=5µ A (Max.) ICCH=5µ A (Max)
● High precision voltage detection (Max Vs± 3%)
● Typical hysteresis voltage 50mV
● Large output current when starting (typical 15mA)

 

Application:

● Control circuit as battery backup memory
● As a measure to prevent power switch operation error
● Used to prevent instantaneous power failure and other system out of control
● As a reset function installed in CPU devices, such as printers, PCS, VTRs, etc.
