ULTRA-SMALL, LOW-INPUT-VOLTAGE, LOW r_ONLOAD SWITCH

Check for Samples: TPS22924C

FEATURES

DESCRIPTION

•

Integrated Single Load Switch

Input Voltage: 0.75 V to 3.6 V

Ultra-Low ON Resistance

The TPS22924C is a small, ultra-low r_ONload switch

with controlled turn on. The devices contain

N-channel MOSFETs that can operate over an input

voltage range of 0.75 V to 3.6 V. An integrated

charge pump biases the NMOS switch to achieve a

minimum switch ON resistance. The switch is

controlled by an on/off input (ON), which is capable of

interfacing directly with low-voltage control signals.

–

r_DS(ON)= 5.7 mΩ at V_IN= 3.6 V

r_DS(ON)= 5.8 mΩ at V_IN= 2.5 V

r_DS(ON)= 5.9 mΩ at V_IN= 1.8 V

r_DS(ON)= 6 mΩ at V_IN= 1.2 V

r_DS(ON)= 8 mΩ at V_IN= 0.75 V

A 1250-Ω on-chip load resistor is added for output

quick discharge when switch is turned off. The rise

time of the device is internally controlled to avoid

inrush current. The TPS22924C features a rise time

of 800 µs at 3.6 V.
