FOR AUTOMOTIVE 105°C OPERATION BUILT-IN DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING)
VOLTAGE DETECTOR WITH SENSE PIN
Rev.1.0_00
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.
