Automotive, 105°C Operation, 36 V, SENSE-Input Voltage Detector with Delay Function (External Delay Time Setting) S-19110AxxH to S-19110HxxH Series

The S-19110 Series is a high-accuracy voltage detector developed using CMOS technology. The detection voltage and release voltage are fixed internally with an accuracy of ±1.5%. It operates with current consumption of 600 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 detection signal and release signal can be delayed by setting a capacitor externally, and the detection delay time accuracy is ±20% (Cn = 3.3 nF, Ta = −40°C to +105°C), the release delay time accuracy is ±20% (Cp = 3.3 nF, Ta = −40°C to +105°C).
Output form is Nch open-drain output.

Caution: This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the purpose, contact to ABLIC Inc. is indispensable.
