3-1. Glossary of terms used in the datasheets for load switch ICs

The following table provides the definitions of major electrical characteristics shown in the datasheets of load switch ICs.

Glossary of terms

Characteristic

Symbol

Description

Input voltage

VIN

The input voltage range in which a load switch IC operates properly

Quiescent current (ON state)

IQ

The amount of quiescent current that flows through a load switch IC when it is on

Quiescent current (OFF state)

IQ(OFF)

The amount of quiescent current that flows through a load switch IC when it is off

Switch leakage current (OFF state)

ISD(OFF)

The amount of leakage current flowing out of the VOUT pin when a load switch IC is off

CONTROL High-level input voltage

VIH

The minimum voltage at which the Control pin of a load switch IC is regarded as being in the logic High state

CONTROL Low-level input voltage

VIL

The maximum voltage at which the Control pin of a load switch IC is regarded as being in the logic Low state

On-resistance

RON

On-resistance between the drain and source of the MOSFET connected between the VIN and VOUT pins

Reverse blocking current

IRB

The amount of current that flows into a load switch IC from the VOUT pin when the voltage at the VOUT pin is higher than the voltage at the VIN pin

Reverse blocking voltage threshold

VRB

The difference in voltage between the VOUT and VIN pins (VOUT-VIN) at which the reverse-current blocking circuit is tripped when VOUT > VIN. VRB is specified for load switch ICs with a true reverse-current blocking function.

Reverse blocking release voltage threshold

VRBR

The difference in voltage between the VOUT and VIN pins (VOUT-VIN) at which the reverse-current blocking circuit is disabled when VIN rises back above VOUT after it is tripped. VRBR is specified for load switch ICs with a true reverse-current blocking function.

Undervoltage lockout (UVLO) rising threshold

VUVL_RI

The threshold voltage at which UVLO is disabled when VIN rises. A load switch IC turns on when VIN exceeds VUVL_RI.

Undervoltage lockout (UVLO) falling threshold

VUVL_FA

The threshold voltage at which UVLO is tripped when VIN falls. A load switch IC is disabled when VIN drops below VUVL_FA.

Overvoltage lockout (OVLO) rising threshold

VOVL_RI

The threshold voltage at which OVLO is tripped when VIN rises. A load switch IC is disabled when VIN exceeds VOVL_RI.

Overvoltage lockout (OVLO) falling threshold

VOLV_FA

The threshold voltage at which OVLO is disabled when VIN falls. A load switch IC is enabled when VIN falls below VOLV_FA.

Output discharge on-resistance

RSD

The on-resistance of the internal N-channel MOSFET connected between the VOUT and GND pins of a load switch IC for discharging the external smoothing capacitor connected to the VOUT pin

Output limited current

ICL

The current level to which the output current is limited by the overcurrent protection function
