Automotive, 105°C Operation, High Side Switch with Current Monitor S-19680 Series

The S-19680 Series, developed by using CMOS technology, is a high side switch with the current monitor function.
When the Pch output transistor is turned on, voltage is supplied to the load connected to the OUT pin. Monitoring the current which flows from the VIN pin to the OUT pin by using two external resistors, the S-19680 Series limits the current so that it does not exceed the set value. Depending on the monitored current value, the S-19680 Series detects the short-circuit status or the open status of the load connected to the OUT pin, and outputs an alarm signal.
In addition, the S-19680 Series has the ON / OFF circuit to control the Pch output transistor's status, ON and OFF, and the thermal shutdown circuit to limit overheating. The hysteresis type or latch type can be selected for the thermal shutdown circuit.

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.
  • The information herein is subject to change without notice.
