(1) See the Application Information section.
(2) In applications where high power dissipation and-or poor package thermal resistance is present, the maximum ambient temperature may
have to be derated and device lifetime may be affected. Maximum ambient temperature (TA(max)) is dependent on the maximum
operating junction temperature (TJ(max)), the maximum power dissipation of the device in the application (PD(max)), and the junction-to-
ambient thermal resistance of the part-package in the application (θJA), and can be approximated by the following equation: TA (max)
TJ(max) – (θJA × PD(max)).

9 Detailed Description
9.1 Overview
The TPS22975 device is a single-channel, 6-A load switch in an 8-pin SON package. To reduce the voltage drop
in high current rails, the device implements an N-channel MOSFET. The device has a configurable slew rate for
applications that require a specific rise-time.
The device prevents downstream circuits from pulling high standby current from the supply by limiting the
leakage current of the device when it is disabled. The integrated control logic, driver, power supply, and output
discharge FET eliminates the need for any external components, which reduces solution size and bill of materials
(BOM) count.

9.3 Feature Description
9.3.1 Adjustable Rise Time
A capacitor to GND on the CT pin sets the slew rate. The voltage on the CT pin can be as high as 15 V;
therefore, the minimum voltage rating for the CT capacitor must be 30 V for optimal performance. An
approximate formula for the relationship between CT and slew rate when VBIAS is set to 5 V is shown in
Equation 1. This equation accounts for 10% to 90% measurement on VOUT and does not apply for CT < 100 pF.
Use Table 1 to determine rise times for when CT = 0 pF.
SR = 0.43ìCT + 26
where
•
•
•
SR is the slew rate (in µs/V)
CT is the capacitance value on the CT pin (in pF)
The units for the constant 26 are µs/V. The units for the constant 0.43 are µs/(V × pF).
(1)
Rise time can be calculated by multiplying the input voltage by the slew rate. Table 1 contains rise time values
measured on a typical device. Rise times shown in Table 1 are only valid for the power-up sequence where VIN
and VBIAS are already in steady state condition before the ON pin is asserted high.

9.3.2 Quick-Output Discharge (QOD) (Optional)
The TPS22975 includes an optional QOD feature. When the switch is disabled, an internal discharge resistance
is connected between VOUT and GND to remove the remaining charge from the output. This resistance has a
typical value of 230 Ω and prevents the output from floating while the switch is disabled. For best results, it is
recommended that the device gets disabled before VBIAS falls below the minimum recommended voltage.
9.3.3 Thermal Shutdown
Thermal shutdown protects the part from internally or externally generated excessive temperatures. When the
device temperature triggers TSD (typical 160°C), the switch is turned off. The switch automatically turns on again
if the temperature of the die drops 20 degrees below the TSD threshold.

10 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
10.1 Application Information
10.1.1 ON and OFF Control
The ON pin controls the state of the switch. ON is active high and has a 1.2-V ON-pin enable threshold, making
it capable of interfacing with low-voltage signals. The ON pin is compatible with standard GPIO logic thresholds.
It can be used with any microcontroller with 1.2 V or higher GPIO voltage. This pin cannot be left floating and
must be driven either high or low for proper functionality.
10.1.2 Input Capacitor (CIN) (Optional)
To limit the voltage drop on the input supply caused by transient inrush currents when the switch turns on into a
discharged load capacitor or short-circuit, a capacitor needs to be placed between VIN and GND. A 1-µF ceramic
capacitor, CIN, placed close to the pins, is usually sufficient. Higher values of CIN can be used to further reduce
the voltage drop during high current applications. When switching heavy loads, it is recommended to have an
input capacitor about 10 times higher than the output capacitor (CL) to avoid excessive voltage drop.
10.1.3 Output Capacitor (CL) (Optional)
Because of the integrated body diode in the NMOS switch, a CIN greater than CL is highly recommended. A CL
greater than CIN can cause VOUT to exceed VIN when the system supply is removed. This could result in current
flow through the body diode from VOUT to VIN. A CIN to CL ratio of 10 to 1 is recommended for minimizing VIN dip
caused by inrush currents during startup; however, a 10 to 1 ratio for capacitance is not required for proper
functionality of the device. A ratio smaller than 10 to 1 (such as 1 to 1) could cause slightly more VIN dip upon
turn-on because of inrush currents. This can be mitigated by increasing the capacitance on the CT pin for a
longer rise time (see the Adjustable Rise Time section).
10.2 Typical Application
For optimal RON performance, it is recommended to have VIN ≤ VBIAS. The device is functional if VIN > VBIAS but it
exhibits RON greater than what is listed in the Electrical Characteristics—VBIAS = 5 V and Electrical
Characteristics—VBIAS = 2.5 V tables.
Figure 31 demonstrates how the TPS22975 can be used to power downstream modules.

10.2.2 Detailed Design Procedure
10.2.2.1 Inrush Current
When the switch is enabled, the output capacitors must be charged up from 0 V to the set value (3.3 V in this
example). This charge arrives in the form of inrush current. Inrush current can be calculated using Equation 2.
Inrush Current = CL × dVOUT/dt
Where:
•
•
•
CL is the output capacitance
dVOUT is the change in VOUT during the ramp up of the output voltage when device is enabled.
dt is the rise time in VOUT during the ramp up of the output voltage when the device is enabled.
(2)
The TPS22975 offers adjustable rise time for VOUT. This feature allows the user to control the inrush current
during turnon. The appropriate rise time can be calculated using the design requirements and the inrush current
equation as shown in Equation 3.
400 mA = 22 µF × 3.3 V/dt
(3)
The value of dt is given by Equation 4.
dt = 181.5 µs
(4)
To ensure an inrush current of less than 400 mA, choose a CT value that yields a rise time of more than 181.5
µs. See the oscilloscope captures in the Application Curves section for an example of how the CT capacitor can
be used to reduce inrush current.

11 Power Supply Recommendations
The supply to the device must be well regulated and placed as close to the device terminal as possible with the
recommended 1-μF bypass capacitor. If the supply is located more than a few inches from the device terminals,
additional bulk capacitance may be required in addition to the ceramic bypass capacitors. If additional bulk
capacitance is required, an electrolytic, tantalum or ceramic capacitor of 1 μF may be sufficient.
The TPS22975 operates regardless of power sequencing order. The order in which voltages are applied to VIN,
VBIAS, and ON does not damage the device as long as the voltages do not exceed the absolute maximum
operating conditions. If voltage is applied to ON before VIN, the slew rate of VOUT can not be controlled.

12 Layout
12.1 Layout Guidelines
For best performance, all traces must be as short as possible. To be most effective, the input and output
capacitors must be placed close to the device to minimize the effects that parasitic trace inductances may have
on normal operation. Using wide traces for VIN, VOUT, and GND helps minimize the parasitic electrical effects
along with minimizing the case to ambient thermal impedance. The CT trace must be as short as possible to
reduce parasitic capacitance.

12.3 Thermal Considerations
The maximum IC junction temperature must be restricted to 125°C under normal operating conditions. To
calculate the maximum allowable dissipation, PD(max) , for a given ambient temperature, use Equation 5 as a
guideline.
TJ(max) - TA
=
P
D(max)
θJA
where
•
•
•
•
PD(max) is the maximum allowable power dissipation
TJ(max) is the maximum allowable junction temperature (125°C for the TPS22975)
TA is the ambient temperature of the device
ΘJA is the junction to air thermal impedance. See the Thermal Information section. This parameter is highly
dependent upon board layout.
(5)
In Figure 34, notice that the thermal vias are located under the exposed thermal pad of the device. This allows
for thermal diffusion away from the device.
