Automotive ICs

Automotive, 125°C Operation, 36 V Input, 600 mA, High Side Switch with Current Monitor S-19683B Series

Automotive high side switch S-19682/3 Series features

This IC, 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 VOUT pin. The current monitor measures the current flowing to the high side switch, outputs the voltage according to the load current, and limits the current value from exceeding the set value.
In addition, this IC has the ON / OFF circuit to control the Pch output transistor's status, ON and OFF, and the thermal shutdown circuit to limit overheating.

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.
