ИС переключателя электропитания – распределение электропитания TPS27082LDDCR

Переключатель силовой нагрузки , настраиваемое время нарастания, высокая сторона, активный высокий

The TPS27082LDDCR is a high-side Load Switch requires very low ON-state quiescent current and offers very low OFF-state leakage thus optimizing system power efficiency. TPS27082L ON/OFF logic interface features hysteresis, thus providing a robust logic interface even under very noisy operating conditions. TPS27082L ON/OFF interface supports direct interfacing to low voltage GPIOs down to 1V. The TPS27082L level shifts ON/OFF logic signal to VIN levels without requiring an external level shifter. TPS27082L features a novel OFF isolation circuit that prevents PMOS from turning ON in applications that may have fast transients, at the VIN pin when the load switch is in the OFF-state.

• Configurable turn-ON and turn-OFF slew rate
• 10µs default minimum output rise time at VIN=5 V
• Configurable turn-on and turnoff slew rate
• Excellent OFF isolation even under fast input transients
• Low ON-resistance, high current PFET
• 1.0V up to 8V NMOS control logic interface with configurable hysteresis
• Very low ON-state quiescent current (down to 1.2µA)
• Very low OFF-state leakage current (typical 100nA)
