FOR AUTOMOTIVE 105°C OPERATION BUILT-IN DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING)
VOLTAGE DETECTOR WITH SENSE PIN
The S-19104/19106 Series is a high-accuracy voltage detector developed using CMOS technology. The detection voltage
is fixed internally with an accuracy of ±3.5% (−VDET(S) ≥ 2.2 V). It operates with current consumption of 500 nA typ.
Apart from the power supply pin, the detection voltage input pin (SENSE pin) is also prepared, so the output is stable even
if the SENSE pin falls to 0 V.
The release signal can be delayed by setting a capacitor externally, and the release delay time accuracy is ±34% (CD =
4.7 nF, Ta = −40°C to +105°C).
Two output forms Nch open-drain output and CMOS output are available.
Caution This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in
the purpose, contact to SII is indispensable.
