TPS22916xx 1-V–5.5-V, 2-A, 60-mΩ Ultra-Low Leakage Load Switch

1 Features

3 Description

•

Input operating voltage range (V_IN): 1 V–5.5 V

Maximum continuous current (I_MAX): 2 A

ON-resistance (R_ON):

– 5 V_IN= 60 mΩ (typ.), 100 mΩ (85°C max.)

– 1.8 V_IN= 100 mΩ (typ.), 150 mΩ (85°C max.)

– 1 V_IN= 200 mΩ (typ.), 325 mΩ (85°C max.)

Ultra-low power consumption:

– ON state (I_Q): 0.5 µA (typ.), 1 µA (max.)

– OFF state (I_SD): 10 nA (typ.), 100 nA (max.)

– TPS22916BL/CL/CNL (I_SD): 100 nA (typ.), 300

nA (max.)

The TPS22916xx is a small, single channel load

switch using a low leakage P-Channel MOSFET for

minimum power loss. Advanced gate control design

supports operating voltages as low as 1 V with

minimal increase in ON-resistance and power loss.

Multiple timing options are available to support

various system loading conditions. For heavy

capacitive loads, the slow turn-on timing in the C

version minimizes the inrush current. In cases with

light capacitive loads, the fast timing in the B version

reduces required wait time.

•

Smart ON pin pulldown (R_PD):

– ON ≥ V_IH(I_ON): 10 nA (max.)

– ON ≤ V_IL(R_PD): 750 kΩ (typ.)

The switch ON state is controlled by a digital input

that is capable of interfacing directly with low-voltage

control signals. Both Active High and Active Low (L)

versions are available. When power is first applied,

a smart pulldown is used to keep the ON pin from

floating until system sequencing is complete. AFter

the ON pin is deliberately driven high (≥V_IH), the smart

pulldown is disconnected to prevent unnecessary

power loss.

Slow Timing in C Version Limits Inrush Current:

– 5-V turn-on time (t_ON): 1400 µs at 5 mV/µs

– 1.8-V turn-on time (t_ON): 3000 µs at 1 mV/µs

– 1-V turn-on time (t_ON): 6500 µs at 0.3 mV/µs

Fast timing in b version reduces wait time:

– 5-V turn-on time (t_ON): 115 µs at 57 mV/µs

– 1.8-V turn-on time (t_ON): 250 µs at 12 mV/µs

– 1-V turn-on time (t_ON): 510 µs at 3.3 mV/µs

Always-ON true Reverse Current Blocking (RCB):

– Activation current (I_RCB): –500 mA (typ.)

– Reverse leakage (I_IN,RCB): –300 nA (max.)

Quick Output Discharge (QOD): 150 Ω (typ.)

(N version has no QOD)

•

The TPS22916xx is available in a small, space

saving 0.78 mm × 0.78 mm, 0.4-mm pitch, 0.5-

mm height 4-pin Wafer-Chip-Scale (WCSP) package

(YFP). The device is characterized for operation over

a temperature range of –40°C to +85°C.
