3 Description

The TPS22920x is a small, space-saving load switch with controlled turn on to reduce inrush current. The device contains a N-channel MOSFET that can operate over an input voltage range of 0.75 V to 3.6 V and switch currents up to 4 A. An integrated charge pump biases the NMOS switch in order to achieve a minimum switch ON resistance (r_ON). The switch is controlled by an on/off input (ON), which is capable of interfacing directly with low-voltage control signals.

The TPS22920x has a 1250-Ω on-chip resistor for quick output discharge when the switch is turned off which insures that the output is not left floating.

The TPS22920x has an internally controlled rise time in order to reduce inrush current.

The TPS22920x is available in an ultra-small, space- saving 8-pin CSP package and is characterized for operation over the free-air temperature range of –40°C to 85°C.

ORDERABLE PART NUMBER	R_ON (TYP) AT 3.6 V	RISE TIME (TYP) at 3.6V	QUICK OUTPUT DISCHARGE⁽¹⁾	BACKSIDE COATING⁽²⁾	ENABLE
TPS22920YZPR	5.3 mΩ	880 µS	Yes	No	Active High
TPS22920YZPRB	5.3 mΩ	880 µS	Yes	Yes	Active High
TPS22920LYZPR	5.3 mΩ	627 µS	Yes	Yes	Active Low

(1) This feature discharges the output of the switch to ground through a 1250-Ω resistor, preventing the output from floating. See Output Pull-Down.

(2) CSP (DSBGA) devices manufactured with backside coating have an increased resistance to cracking due to the increased physical strength of the package. Devices with backside coating are highly encouraged for new designs.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
