TPS2052P Equivalent & Substitute Parts

Part Overview

The TPS2052P is a power management integrated circuit (PMIC) functioning as an N-Channel power switch driver with 1:2 output configuration. Manufactured by Texas Instruments, this component operates as a high-side switch with 500mA maximum output current and integrated fault protection including current limiting, over-temperature, and under-voltage lockout (UVLO). The TPS2052P is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and new design alternatives.

Substitute Part Grouping Explanation

Substitution of the TPS2052P is determined by the following critical parameters: output configuration (high-side), output type (N-Channel), maximum output current (500mA), on-resistance (80mOhm typical), load voltage range (2.7V ~ 5.5V), and fault protection features (current limiting, over-temperature, UVLO). The number of outputs and input type (inverting vs. non-inverting) define functional equivalence levels.

Substitutes are grouped into two categories:

Manufacturer Recommended Substitute: TPS2052AD provides direct functional equivalence with identical electrical specifications but differs in mounting technology (surface mount 8-SOIC vs. through-hole 8-DIP) and product status (active).

Parametric Equivalents: TPS2041P, TPS2042P, and TPS2051P share core electrical characteristics (500mA output, 80mOhm Rds On, 2.7V ~ 5.5V load voltage, high-side configuration) but differ in output count and input logic configuration. TPS2041P and TPS2051P feature single output (1:1 ratio) versus the dual output (1:2 ratio) of TPS2052P. TPS2042P maintains the 1:2 output configuration. Input type varies: TPS2041P and TPS2042P use inverting logic, while TPS2051P and TPS2052P use non-inverting logic.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Functionality): TPS2052AD is the manufacturer-recommended substitute, providing identical electrical performance and fault protection. The primary difference is packaging: TPS2052AD uses surface-mount 8-SOIC technology versus the through-hole 8-DIP of TPS2052P. TPS2052AD holds active product status, ensuring long-term availability and support. Operating temperature range narrows to 0°C ~ 85°C compared to TPS2052P's -40°C ~ 85°C; verify this meets application requirements for extended temperature operation.

For Single-Output Applications: TPS2041P and TPS2051P both provide 1:1 output configuration with identical electrical specifications. TPS2041P features inverting input logic and active product status. TPS2051P provides non-inverting input logic matching TPS2052P but carries "Not For New Designs" status. Both maintain through-hole 8-DIP packaging and -40°C ~ 85°C operating temperature range.

For Dual-Output with Inverting Logic: TPS2042P maintains the 1:2 output configuration with inverting input logic, active product status, and through-hole 8-DIP packaging. Operating temperature range matches TPS2052P at -40°C ~ 85°C.

All substitute parts maintain ROHS3 compliance and identical fault protection architecture. Selection should prioritize active product status for new designs and long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can TPS2052AD directly replace TPS2052P in existing PCB designs?

A: TPS2052AD provides electrical equivalence but requires PCB redesign due to package differences. TPS2052P uses through-hole 8-DIP mounting while TPS2052AD uses surface-mount 8-SOIC. Footprint, pin spacing, and assembly process differ significantly. For through-hole designs, TPS2042P or TPS2041P maintain the 8-DIP package.

Q: What is the difference between inverting and non-inverting input types?

A: Input type determines logic polarity. Non-inverting inputs (TPS2052P, TPS2051P) activate the output when the input signal is high. Inverting inputs (TPS2041P, TPS2042P) activate the output when the input signal is low. Circuit design and control logic must accommodate this difference.

Q: Why does TPS2052AD have a narrower operating temperature range?

A: TPS2052AD operates from 0°C ~ 85°C versus TPS2052P's -40°C ~ 85°C. Applications requiring extended low-temperature operation below 0°C must use TPS2042P, TPS2041P, or TPS2051P, which all support -40°C ~ 85°C.

Q: Can I use a single-output part (TPS2041P or TPS2051P) in place of the dual-output TPS2052P?

A: Single-output parts are not direct replacements for dual-output applications. Use only if your circuit requires control of a single load. TPS2042P maintains dual-output functionality.

Q: What is the significance of "Not For New Designs" status on TPS2051P?

A: This status indicates the part is available but not recommended for new product development. For new designs, prioritize TPS2041P (active status, inverting logic) or TPS2042P (active status, dual output, inverting logic).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TPS2052P, TPS2052AD, TPS2041P, TPS2042P, and TPS2051P are all ROHS3 compliant, meeting environmental and regulatory requirements.
