Automotive, 105°C Operation, 36 V, Supply Voltage Divided Output, Voltage Detector with SENSE Pin Reverse Connection Protection S-19117/19119xxxH Series

This IC, developed using CMOS technology, is a high-accuracy voltage detector with the supply voltage divided output. The detection voltage and release voltage are fixed internally with an accuracy of ±1.5%.
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 voltage (VSENSE) falls to 0 V. The SENSE pin also has a built-in reverse connection protection circuit that reduces current in the SENSE pin during a reverse connection.
The release signal can be delayed by setting a capacitor externally, and the release delay time accuracy is ±15% (CD = 3.3 nF). The output form is Nch open-drain output.
The supply voltage divided output is prepared in this IC. The supply voltage divided output is a function that divides the VSENSE into VSENSE/6, VSENSE/8, VSENSE/12 or VSENSE/14 and outputs the voltage. For example, this function makes it possible that the IC connects to a low voltage microcontroller A/D converter directly and the microcontroller monitors a battery voltage.

Parts List

  • U(Ux), S and G at the end of the product name of ABLIC Inc. were used to indicate different material specifications as “environmental code”,
    however, these have now been unified into “lead-free and halogen-free” and are identical in terms of environmental quality.
  • Note: Lead-free plating other than 100% Sn is applied to some limited old products, therefore, please contact our sales representatives for details.
  • These descriptions may be different from the actual product name and parameter.
    Please confirm the product name and specifications with the data sheet again.
