DESCRIPTION
• Configurable Turn-ON and Turn-OFF Slew
The TPS27082L IC is a high side load switch that
Rate
integrates a Power PFET and a control circuit in a
– 10µsec Default Minimum Output Rise Time
tiny TSOT-23 package. TPS27082L requires very low
at VIN=5V
ON-state quiescent current and offers very low OFF-
state leakage thus optimizing system power
• Configurable Turn-ON and Turn-OFF Slew
efficiency.
Rate
• Supports a Wide Range of VIN 1.2V up to 8V
TPS27082L ON/OFF logic interface features
hysteresis, thus providing a robust logic interface
• Excellent OFF Isolation Even Under Fast Input
even under very noisy operating conditions.
Transients
TPS27082L ON/OFF interface supports direct
• 1.0V up to 8V NMOS Control Logic Interface
interfacing to low voltage GPIOs down to 1V. The
With Configurable Hystersis
TPS27082L level shifts ON/OFF logic signal to VIN
• Fully Protected Against ESD (All Pins)
levels without requiring an external level shifter.
– HBM 2kV, CDM 500V
TPS27082L features a novel OFF isolation circuit that
prevents PMOS from turning ON in applications that
• Very Low ON-state Quiescent Current (Down
may have fast transients, at the VIN pin when the
to 1.2µA)
load switch is in the OFF-state.
• Very Low OFF-state Leakage Current (Typ
100nA)
• Available in 2.9mm x 1.6mm x 0.75mm SOT-23
