TPS2013DR

TPS2013DR Description

The TPS2013DR from Texas Instruments is a high-side, N-channel power distribution switch designed for general-purpose load switching applications. This single-channel device operates within a load voltage range of 2.7V to 5.5V, making it suitable for low-voltage systems. With a 1:1 input-to-output ratio, it ensures efficient power delivery while minimizing signal distortion. The surface-mount 8-SOIC package (delivered in Tape & Reel) facilitates compact PCB integration. Although marked as "Not For New Designs", it remains a reliable solution for legacy systems requiring current limiting and thermal protection.

TPS2013DR Features

• Low Rds(On): 75mΩ (typical) ensures minimal power loss and high efficiency.
• Robust Protection: Integrated fixed current limiting (1.5A max) and over-temperature shutdown safeguard against faults.
• Simplified Control: On/Off interface for straightforward logic-level switching.
• No External Supply Needed: Operates without a separate Vcc/Vdd, reducing component count.
• Compliance: ROHS3 and REACH compliant, with MSL 1 (unlimited) for extended shelf life.
• Wide Load Range: Supports 2.7V–5.5V loads, ideal for USB peripherals, portable devices, and battery-powered systems.

TPS2013DR Applications

• USB Power Management: Hot-swappable ports and hub power control.
• Portable Electronics: Battery cutoff and load switching in handheld devices.
• Industrial Systems: Relay/actuator drivers with built-in fault protection.
• Automotive Accessories: Low-voltage auxiliary power distribution.
• Legacy Upgrades: Cost-effective replacement for older power switches.

Conclusion of TPS2013DR

The TPS2013DR excels in low-voltage, high-efficiency switching with its low Rds(On) and integrated protections. While not recommended for new designs, its reliability, compact form factor, and compliance make it a pragmatic choice for existing systems requiring robust power management. Ideal for space-constrained or legacy applications, it balances performance with ease of integration.
