TPS22930 SLVSBL3D – NOVEMBER 2012 – REVISED JULY 2021 TPS22930 Ultra Small, Low On-Resistance Load Switch with Controlled Turn-On 1 Features 3 Description • • The TPS22930 is a small, low RON load switch with controlled turn on. The device contains a Pchannel 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 TPS22930 is active high enable. • • • • • • • • Integrated single channel load switch Ultra small four terminal wafer-chip-scale package (nominal dimensions shown see addendum for details) – 0.9 mm × 0.9 mm, 0.5 mm pitch, 0.5-mm height (YZV) Input voltage range: 1.4 V to 5.5 V Ultra low RON resistance – RON = 35 mΩ at VIN = 5 V – RON = 36 mΩ at VIN = 3.6 V – RON = 49 mΩ at VIN = 1.8 V 2-A maximum continuous switch current Low quiescent current (< 3 µA) Low control input threshold enables use of 1.2-V/1.8-V/2.5-V/3.3-V logic Controlled slew rate Under voltage lockout Reverse current protection when disabled 2 Applications • • • • • • • Smartphone / wireless handsets Portable industrial / medical equipment Portable media players Point of sales terminals GPS navigation devices Digital cameras Portable instrumentation The TPS22930 device provides circuit breaker functionality by disabling the body diode during reverse voltage (also known as reverse current) situations. Reverse current protection is active only when the power-switch is disabled (off). The device disengages the body diode when the output voltage (VOUT) is driven higher than the input (VIN) to stop the flow of current towards the input side of the switch. Additionally, under-voltage lockout (UVLO) protection turns the switch off if the input voltage is too low. The slew rate of the device is internally controlled in order to avoid inrush current. The TPS22930 is available in an ultra-small, spacesaving 4-pin CSP package and is characterized for operation over the free-air temperature range of – 40°C to 85°C.

A low enable threshold makes it capable of interfacing directly with low voltage control signals. In the off state, the device has very low leakage current during off state. This prevents downstream circuits from pulling high standby current from thee supply. When turning on, the output will rise with a controlled slew rate to limit inrush current. The device will also disengage the body diode when disabled to provide reverse current protection. The undervoltage lockout (UVLO) threshold will ensure the switch is turned off and will block reverse current if the VIN power supply is removed 8.2 Functional Block Diagram VIN Reverse Current Protection UVLO Control Logic ON GND VOUT 8.3 Feature Description Table 8-1. Feature List (1) DEVICE RON (TYP) AT 4.2 V RISE TIME AT 4.2 V (TYP) QUICK OUTPUT DISCHARGE(1) MAXIMUM CONTINUOUS CURRENT ENABLE TPS22930A 35 mΩ 5.4 µs No 2A Active High This feature discharges output of the switch to GND through a resistor, preventing the output from floating when the pass FET is disabled. 8.3.1 On And Off Control The ON pins control the state of the switch. Asserting ON high enables the switch. ON is active high and has a low threshold, making it capable of interfacing with low-voltage signals. The ON pin is compatible with standard GPIO logic threshold. It can be used with any microcontroller with 1.2V or higher GPIO voltage. 8.3.2 UVLO UVLO turns off the switch if the input voltage drops below the under voltage lockout threshold. With the ON pin active, the input voltage rising above the under voltage lockout threshold will allow a controlled turn-on of the switch to limit current over-shoot. 14 Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated TPS22930 www.ti.com SLVSBL3D – NOVEMBER 2012 – REVISED JULY 2021 The maximum UVLO of the TPS22930A is 1.2 V. This is under the minimum VIN voltage and meets the system UVLO requirements. Once the device is disabled through UVLO, it will block reverse current in the case a voltage is applied to VOUT 8.3.3 Reverse Current Protection Reverse current protection (RCP) is only active when ON is asserted low. When ON is asserted high, current can flow from VOUT to VIN or from VIN to VOUT. This allows the device to function as a bi-directional switch when enabled. 8.4 Device Functional Modes Table 8-2 describes the state of the switch and the reverse current protection as determined by the ON pin.

TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality. 9.1 Application Information 9.1.1 Input Capacitor (Optional) To limit the voltage drop on the input supply caused by transient in-rush currents when the switch turns on into a discharged load capacitor or short-circuit, it is recommended that a capacitor 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 application. When switching heavy loads, it is recommended to have an input capacitor about 100 times higher than the output capacitor to avoid excessive voltage drop; however, a 100 to 1 ratio is not required for proper functionality of the device. 9.1.2 Output Capacitor (Optional) Due to the integrated body diode in the PMOS 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 100 to 1 is recommended for minimizing VIN dip caused by inrush currents during startup; however, a 100 to 1 ratio is not required for proper functionality of the device. 9.2 Typical Application Power Supply VIN ON CIN VOUT ON CL RL OFF TPS22930 GND GND Figure 9-1.

ON = 5 V Figure 9-2. UVLO Response 10 Power Supply Recommendations The device is designed to operate from a VIN range of 1.5 V to 5.5 V. The power supply should be well regulated and placed as close to the device terminals as possible. It must be able to withstand all transient and load current steps. in most situations, using an input capacitance of 1 µF is sufficient to prevent the supply voltage from dipping when the switch is turned on. In cases where the power supply is slow to respond to a large transient current or large load current step, additional bulk capacitance may be required on the input 11 Layout 11.1 Layout Guidelines For best performance, all traces should be as short as possible. To be most effective, the input and output capacitors should 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 ON pin cannot be left floating and must be driven either high or low for proper functionality. Figure 11-1 shows an example of a layout.

Layout Recommendation 11.3 Thermal Considerations The maximum IC junction temperature should be restricted to 125°C under normal operating conditions. To calculate the maximum allowable dissipation, PD(max) for a given output current and ambient temperature, use the following equation as a guideline: PD(max) = TJ(max) - TA θJA (1) where • • • • PD(max) = maximum allowable power dissipation TJ(max) = maximum allowable junction temperature (125°C for the TPS22930) TA = ambient temperature of the device ΘJA = junction to air thermal impedance. See Thermal Information table. This parameter is highly dependent upon board layout. The power dissipated by the device depends on the RON of the device at a given VIN. To calculate the amount of power being dissipated by the device, use the following equation: PIR = I2 ´ RON (2) where • • • PIR = power dissipated by the device I = load current in amperes RON = resistance of the device in Ohms at a given VIN (see Electrical Characteristics table) The result from Equation 2 should always be less than or equal to the result from Equation 1. 18 Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated TPS22930 www.ti.com SLVSBL3D – NOVEMBER 2012 – REVISED JULY 2021 12 Device and Documentation Support 12.1 Receiving Notification of Documentation Updates To receive notification of documentation updates, navigate to the device product folder on ti.com.
