Replacement verdict
Compatible functional replacement candidate
The TPS22950YBHR and TPS22916CYFPR are both single-channel load switches with comparable on-resistance and current handling, making the TPS22916CYFPR a viable functional substitute in many low-voltage power-rail applications. However, designers must validate the differences in quiescent current, switching behavior, and package footprint before committing to a drop-in replacement.

Key electrical and mechanical differences between the two devices
| Parameter | TPS22950YBHR | TPS22916CYFPR | Why it matters |
|---|---|---|---|
| Input Voltage Range (VIN) | 0.5 V to 5.5 V | 1.0 V to 5.5 V | Defines the supply voltages the load switch can safely pass; a narrower minimum on one device limits low-voltage operation. |
| Continuous Output Current (Max) | 2 A | 2 A | Sets the maximum load current the switch can carry without exceeding its ratings. |
| On-Resistance (RON) at 5 V | 13 mΩ (typical) | 20 mΩ (typical) | Lower RON reduces voltage drop and power loss, improving efficiency and load regulation. |
| Quiescent Current (IQ) | 7 µA (typical) | 0.5 µA (typical) | Affects standby power consumption, critical for battery-powered and always-on systems. |
| Control Logic Threshold (VIL/VIH) | VIL 0.4 V / VIH 1.2 V | VIL 0.4 V / VIH 1.0 V | Determines compatibility with the driving GPIO logic levels; mismatches can cause unreliable enable/disable. |
| Package | 6-pin DSBGA (WCSP) | 6-pin DSBGA (WCSP) | Footprint and pinout must match for drop-in board replacement. |
| Operating Temperature Range | -40 °C to 85 °C | -40 °C to 105 °C | Wider temperature range supports harsher environments and higher ambient operation. |
| Reverse Current Blocking | Yes | Yes | Prevents current from flowing back from output to input when the switch is off, protecting upstream circuitry. |
| Quick Output Discharge | Yes | Yes | Ensures the output rail is actively discharged when disabled, avoiding floating rails and unintended power sequencing. |

Frequently asked questions
What are the key differences between the TPS22950YBHR and TPS22916CYFPR load switches?
The TPS22950YBHR is a 5.5 V, 3.5 A load switch with adjustable rise time, quick output discharge, and thermal shutdown, housed in a 6-pin WSON (2 mm x 2 mm) package. The TPS22916CYFPR is a 5.5 V, 2 A load switch with a fixed rise time, quick output discharge, and reverse current blocking, housed in a 4-pin DSBGA (0.8 mm x 0.8 mm) package. Key differences include current rating, package size, pin count, and feature set.
Can the TPS22950YBHR and TPS22916CYFPR be used interchangeably in the same design?
No, they are not pin-to-pin or functionally interchangeable. The TPS22950YBHR has 6 pins in a 2 mm x 2 mm WSON package, while the TPS22916CYFPR has 4 pins in a 0.8 mm x 0.8 mm DSBGA package. Their pinouts, footprints, and control interfaces differ, so a direct drop-in replacement is not possible without PCB redesign and validation.
Which device supports a higher continuous output current?
The TPS22950YBHR supports a higher continuous output current of 3.5 A, whereas the TPS22916CYFPR supports up to 2 A. The actual allowable current depends on thermal conditions, PCB layout, and ambient temperature per the respective datasheets.
Do both devices provide quick output discharge (QOD)?
Yes, both the TPS22950YBHR and TPS22916CYFPR include quick output discharge. When the switch is disabled, an internal pull-down resistor discharges the output capacitance to prevent floating voltages.
Does the TPS22916CYFPR have reverse current blocking?
Yes, the TPS22916CYFPR features reverse current blocking, which prevents current from flowing from the output back to the input when the switch is disabled or when the output voltage exceeds the input voltage. The TPS22950YBHR does not include reverse current blocking.
What are the input voltage ranges for these two load switches?
Both the TPS22950YBHR and TPS22916CYFPR operate over an input voltage range of 1.0 V to 5.5 V, making them suitable for low-voltage and standard 5 V rails.
Which device offers an adjustable rise time?
The TPS22950YBHR provides an adjustable rise time via an external capacitor on the CT pin, allowing designers to control inrush current. The TPS22916CYFPR has a fixed rise time and does not offer external adjustment.
What are the package and pin count differences between the TPS22950YBHR and TPS22916CYFPR?
The TPS22950YBHR is supplied in a 6-pin WSON package measuring 2.00 mm x 2.00 mm, while the TPS22916CYFPR is supplied in a 4-pin DSBGA package measuring 0.80 mm x 0.80 mm. The DSBGA package is significantly smaller and requires a different PCB land pattern.
