Texas Instruments TPS25200QDRVTQ1

Overview

TPS25200QDRVTQ1 from Texas Instruments is an AEC-Q100 qualified automotive-grade 5-V eFuse with precision adjustable current limit (85 mA to 2.7 A), overvoltage clamp (5.25–5.55 V), and 7.6-V input overvoltage lockout. It integrates a 67-mΩ high-side N-channel MOSFET, reverse current blocking, and thermal shutdown for robust load protection in USB power delivery systems.

For engineers reviewing the TPS25200QDRVTQ1 datasheet, TPS25200QDRVTQ1 pinout, TPS25200QDRVTQ1 application, or TPS25200QDRVTQ1 equivalent, key selection considerations include ±6.3% current-limit accuracy at 2.7 A, 3.5-μs short-circuit response, 0.6-μs OVLO response, 2.5–6.5-V operating range, and WSON-6 package with exposed thermal pad for automotive USB port protection.

Technical Context

The TPS25200QDRVTQ1 implements dual thermal protection: OTSD1 triggers at 135°C during current-limit events with 20°C hysteresis, while OTSD2 activates at 155°C regardless of operating mode. Its overvoltage clamp uses internal Zener regulation to hold VOUT at 5.4 V when VIN is between 5.4 V and 7.6 V, preventing downstream damage without external components.

Current limiting is set via RILIM resistor (36 kΩ–1100 kΩ), sourcing regulated current from the ILIM pin; the device enters constant-current mode upon overload, reducing VOUT while maintaining precise IOS. The FAULT pin provides deglitched (8-ms) open-drain reporting for overcurrent, overtemperature, and OVLO faults-excluding OVC mode-to avoid false triggers during capacitive load startup.

FAQ

What is the maximum continuous output current supported by the TPS25200QDRVTQ1?

The TPS25200QDRVTQ1 supports up to 2.4 A of continuous output current under recommended operating conditions (TJ ≤ 125°C, VIN = 2.5–6.5 V). This rating assumes adequate PCB copper area for thermal dissipation via the exposed thermal pad. At higher ambient temperatures or with limited heatsinking, derating applies per the RθJB = 36.1°C/W thermal metric.

How does the TPS25200QDRVTQ1 respond when input voltage exceeds 7.6 V?

When VIN exceeds 7.6 V, the TPS25200QDRVTQ1 immediately disables its internal MOSFET within 0.6 μs and asserts the FAULT pin low. The device remains latched off until VIN drops below the UVLO release threshold (~2.35 V) and EN is cycled. No automatic retry occurs-this is a hard shutdown to prevent damage during sustained overvoltage.

Can the TPS25200QDRVTQ1 be used with input voltages below 2.5 V?

No-the TPS25200QDRVTQ1 requires a minimum input voltage of 2.5 V to operate correctly, as specified in the Recommended Operating Conditions table. Below this, the UVLO circuit holds the device disabled and OUT remains disconnected. Attempting operation at 2.3 V or lower results in undefined behavior and is outside guaranteed specifications.

What is the purpose of the 300-kΩ resistor shown tied to the EN pin in the datasheet schematic?

The 300-kΩ resistor serves as a safe pullup from IN to EN, ensuring the TPS25200QDRVTQ1 enables automatically when power is applied-while limiting EN voltage to ≤6.5 V via internal Zener clamping. This eliminates the need for an external logic driver in simple always-on applications and prevents EN from floating, which could cause erratic switching.

Does the TPS25200QDRVTQ1 provide reverse current blocking when disabled?

Yes-the TPS25200QDRVTQ1 blocks reverse current flow from OUT to IN when EN is low or during UVLO/OVLO shutdown. This is achieved via the internal N-channel MOSFET's body diode orientation and gate control logic. Measured reverse leakage is ≤5 µA at 6.5 V OUT and 25°C, ensuring no backfeed into upstream sources during sleep or fault states.
