FAQs

What is TPS2021D?

The TPS2021D is a dual current-limited power distribution switch designed by Texas Instruments. It is ideal for applications requiring protection against overcurrent and short circuits in USB ports, portable devices, and industrial equipment.

How Does TPS2021D Work?

The TPS2021D works by monitoring the output current and limiting it to a safe level in the event of a fault condition such as overcurrent or short circuit. It provides automatic recovery after the fault condition is removed, ensuring continuous and reliable power distribution.

How Many Pins does TPS2021D have and What are the Functions of the Pinout Configuration?

The TPS2021D is housed in a 10-pin VSON (Very Small Outline No-lead) package. The pinout configuration includes:

IN1, IN2: Input power supply pins.
OUT1, OUT2: Output power switch pins.
Fault1, Fault2: Fault status indication pins for each channel.
EN1, EN2: Enable control pins for each channel.
GND: Ground pin.
VCC: Power supply pin for control logic.

What are the Pros and Cons of TPS2021D?

Pros:

Overcurrent Protection: Provides robust protection against overcurrent and short circuits.
Automatic Recovery: Enables automatic recovery after fault conditions are cleared.
Dual Channels: Supports dual power distribution with independent control and fault indication for each channel.
Low RDS(on): Low on-resistance minimizes voltage drop across the switch, reducing power dissipation.
Compact Package: VSON package offers space-efficient and thermally efficient power switch design.

Cons:

External Components: May require additional external components such as input capacitors for enhanced stability and ESD protection.
Complexity: Requires understanding of fault indications and control logic for proper system integration.
Thermal Considerations: Heat dissipation and thermal management may need to be addressed in high-power applications.

Are There Any Equivalents/Alternatives to TPS2021D for Recommendation?

The TPS2022 from Texas Instruments is a similar dual current-limited power distribution switch with additional features.
Alternatives to the TPS2021D include the LTC4236 from Analog Devices and the MAX14756 from Maxim Integrated.
