Ultra-Small, Low on Resistance Load Switch with Controlled Turn-on

Check for Samples: TPS22913

FEATURES

DESCRIPTION

The TPS22913 is a small, low r_ONload switch with

controlled turn on. The device contains a P-channel

MOSFET that can operate over an input voltage

range of 1.4 V to 5.5 V. The switch is controlled by an

on/off input (ON), which is capable of interfacing

directly with low-voltage control signals. The

TPS22913 is active high enable.

Integrated Single Load Switch

Ultra Small CSP-4 Package 0.9mm × 0.9mm,

0.5mm Pitch

•

Input Voltage Range: 1.4-V to 5.5-V

Low ON-Resistance

–

r_ON= 60-mΩ at VIN = 5-V

r_ON= 61-mΩ at VIN = 3.3-V

r_ON= 74-mΩ at VIN = 1.8-V

r_ON= 84-mΩ at VIN = 1.5-V

The TPS22913 contains

a 150-Ω on-chip load

resistor for quick output discharge when the switch is

turned off. The rise time of the device is internally

controlled in order to avoid inrush current. The

TPS22913 family has various slew rate options (see

Table 1).

Under-Voltage Lock Out

The TPS22913 device provides circuit breaker

functionality by latching off the power-switch during

reverse voltage situations. An internal reverse voltage

comparator disables the power-switch when the

output voltage is driven higher than the input (V_IN) to

quickly (10µs typ) stop the flow of current towards the

input side of the switch. The reverse current

protection is active when the power switch is enabled

(ON). Additionally, during under-voltage lockout

(UVLO), or when the switch is disabled, no reverse

current can flow as the switch body diode is not

engaged.
