The device contains a low Rds(ON) N-channel MOSFET that can operate over an input voltage range of 0.8 V to 5.5 V and can support a maximum continuous current of up to 4-A. The switch is controlled by an active high on/off input (ON), which is capable of interfacing directly with low-voltage GPIO control signals. In the TPS22967, a 225-Ω on-chip load resistor is added for quick output discharge (QOD). When the switch is turned off, the output of the switch is discharged to ground through the 225-Ω load resistor. The rise time of the device is internally controlled in order to avoid in-rush current and can be adjusted using an external ceramic capacitor on the CT pin. The TPS22967 is available in a small, space-saving 2mm x 2mm 8-pin SON package with integrated thermal pad allowing for high power dissipation. 1.1 Typical Applications • • • • • • • • 1.2 Features • • • • • • • • 2 Ultrabooks™ Notebooks/Netbooks Tablet PC Consumer Electronics Set-top Boxes/Residential Gateways Industrial Systems Telecom Systems Solid State Drivers (SSD) Integrated single channel load switch Input voltage range: 0.8V to 5.5V Ultra-low on-resistance (22 mΩ typical) 4A maximum continuous switch current Low threshold control input Adjustable slew-rate control Quick Output Discharge transistor SON 8-pin package with thermal pad TPS22967EVM-023 Single 4A Load Switch Copyright © 2013, Texas Instruments Incorporated SLVU951 – August 2013 Submit Documentation Feedback Electrical Performance Specifications www.ti.com 2 Electrical Performance Specifications ELECTRICAL CHARACTERISTICS Unless otherwise noted, the specification in the following table applies over the operating ambient temperature –40°C ≤ TA ≤ 85°C (Full) and VBIAS = 5.0 V.

VBIAS voltage must be present for the device to function. Place a shunt across JP1 to connect VBIAS to VIN voltage source, if VIN supply is used below 2.5V remove the shunt and connect VBIAS voltage to a voltage source greater or equal to 2.5V. 5.4 RON Test Procedure 1. Setup the EVM per Figure 5. 2. Set SOURCE1 level to 5.0V. 3. Place a shunt on JP2 shorting pins 1 to 2. This connects ON to VIN voltage, ON voltage must be between 1.2V and 5.5V for a valid ON state. (When testing RON it is desired to have the switch operating in the always ON condition.) 4. Place a load on VOUT. 5. Turn on SOURCE1. 6. Record the voltage reading from Meter1, record the input current reading from Source1. Calculate RON by dividing Meter1 voltage level by the current reading from Source1. The results will be the RON value for the Switch. 7. Turn off Source1. 5.5 Trise/Ton Tfall/Toff Test Procedure 1. Set up the EVM per Figure 6. 2. Set SOURCE1 level to 5.0V VBIAS is operational between 2.5V and 5.25V, Datasheet limits are specified with VBIAS set at 5.0V. 3. Remove shunt from JP2. 4. Place a load on VOUT1 (a 10Ω 3.25W resistor is recommended for this test). 5. Set signal generator outputs to 0-2Vpp levels, 10–100Hz, and 25% duty cycle. Connect signal generator output to TP2. 6. Turn on SOURCE1. 7. Turn ON the signal generator output. 8. Trise and Ton can be observed from the oscilloscope channel2. A detailed description of tR, tON, tF, and tOFF are listed in the TPS22967 Datasheet under the Switching Characteristics Section. 9. Turn off Source1, and the signal generator output. 6 Performance Data and Typical Characteristic Curves Figure 7 through Figure 8 present typical performance curves for TPS22967EVM-023. 10 TPS22967EVM-023 Single 4A Load Switch Copyright © 2013, Texas Instruments Incorporated SLVU951 – August 2013 Submit Documentation Feedback Performance Data and Typical Characteristic Curves www.ti.com 6.1 Trise/Tfall Curves Figure 7.
