Product Folder Sample & Buy Support & Community Tools & Software Technical Documents TPS22920, TPS22920L SLVSAY8D – JUNE 2011 – REVISED JANUARY 2016 TPS22920x 3.6-V, 4-A, 5.3-mΩ On-Resistance, Integrated Load Switch with Controlled Turn-on 1 Features 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 (rON). The switch is controlled by an on/off input (ON), which is capable of interfacing directly with low-voltage control signals. 1 • • • • • • • • Input Voltage Range: 0.75 V to 3.6 V Integrated Load Switch Integrated Pass-FET rDSON = 2 mΩ (Typ) at 3.6 V Typical ON-Resistance – rON = 5.3 mΩ at VIN = 3.6 V – rON = 5.4 mΩ at VIN = 2.5 V – rON = 5.5 mΩ at VIN = 1.8 V – rON = 5.8 mΩ at VIN = 1.2 V – rON = 6.1 mΩ at VIN = 1.05 V – rON = 7.3 mΩ at VIN = 0.75 V CSP-8 Package 0.9 mm × 1.9 mm, 0.5 mm Pitch 4-A Maximum Continuous Switch Current Shutdown Current 5.5-µA Max ON-Logic Available in Both Active High/Low: – TPS22920 is Active High – TPS22920L is Active Low Low Threshold Control Input Controlled Slew-Rate to Avoid Inrush Current Quick Output Discharge Resistor ESD Performance Tested Per JESD 22 – 4000-V Human-Body Model (A114-B, Class II) – 1000-V Charged-Device Model (C101) 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, spacesaving 8-pin CSP package and is characterized for operation over the free-air temperature range of –40°C to 85°C.

See Output Pull-Down. 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. 6 Pin Configuration and Functions 8-PIN YZP PACKAGE D D C C B B A A 2 1 1 LASER MARKING VIEW 2 BUMP VIEW Pin Functions PIN I/O DESCRIPTION NAME NO.
