TPS2370DR Обзор
A PoE power interface switch is the component that connects a powered device to the power delivered through an Ethernet cable. It sits in the power path after cable-side network isolation and helps a powered device receive or reject power according to the Ethernet PoE system. In this product family, the TPS2370 is specifically identified as an IEEE 802.3af power interface switch for PoE powered devices.
The principal verified feature is IEEE 802.3af compatibility. This standard is associated with 10/100/1000BASE-T Ethernet applications and defines the framework for supplying power over standard Ethernet cabling. The TPS2370DR therefore targets networking equipment that needs a dedicated PoE interface rather than a general-purpose voltage regulator or conventional power switch.
The TPS2370DR uses Texas Instruments’ DR package designation, identified in the supplied results as an 8-SOIC or SOP8 package. Surface-mount construction supports compact PCB layouts, while the eight-pin package leaves the device easy to inspect and replace during manufacturing. The verified distributor information also classifies it as a specialized interface IC and power-supply support circuit.
Typical application areas include PoE-powered network cameras, VoIP phones, wireless access points, Ethernet switches, and other powered devices connected through Ethernet infrastructure. The exact power budget, current handling, protection behavior, and thermal performance must be confirmed from the manufacturer datasheet before final circuit design. This page preserves the verified product identity and distinguishes it from functionally similar, but not necessarily pin-compatible, alternatives.

Типичное применение
TPS2370DR подходит для 6 применениеs: PoE IP Camera Interface, Wireless Access Point Power, VoIP Phone Power Interface, PoE Ethernet Switch, Industrial Networked Sensor, Remote Telemetry Terminal.
PoE IP Camera Interface
The TPS2370DR is relevant to an IEEE 802.3af PoE power path for an IP camera because the verified Texas Instruments description identifies it as a power interface switch for PoE powered devices. The device would be placed in the system’s cable-side power interface area, after the required Ethernet isolation and before the protected downstream supply. Its suitability depends on matching the camera’s load, fault requirements, and thermal conditions to the manufacturer datasheet. The supplied data does not provide a verified current rating or pin map, so the camera design must be reviewed against those missing limits before release.
Рекомендуется
Wireless Access Point Power
A wireless access point can use the TPS2370DR as the dedicated PoE interface element when the equipment is designed around IEEE 802.3af power delivery over Ethernet. The switch supports the system concept of receiving power from a PoE-capable network rather than relying only on a local adapter. Engineering must verify the access point’s load current, startup behavior, cable and magnetics requirements, and thermal margin against the exact TPS2370 ratings. Because the supplied verified material does not expose those limits, they remain mandatory datasheet checks rather than assumptions.
Рекомендуется
VoIP Phone Power Interface
The TPS2370DR is applicable to a VoE or PoE-powered telephone because the verified product description names IEEE 802.3af PoE powered devices as its target application. In a phone design, the device can form part of the power-delivery interface after network-side isolation, allowing the phone to operate from Ethernet power. The design team must confirm whether the phone’s load, auxiliary-power behavior, and fault conditions fit the exact TPS2370 specifications. No verified electrical thresholds were provided, so this passage does not claim a particular current or power class.
Рекомендуется
PoE Ethernet Switch
In a PoE-capable Ethernet switch, the TPS2370DR can be evaluated for the powered-device interface function associated with IEEE 802.3af. Its role is distinct from the Ethernet data path: it supports the power interface for a compliant powered device while the switch’s magnetics, data channels, and system controller handle network communication separately. The candidate should be checked for the required operating voltage, current, protection, and thermal behavior using the official TPS2370 documentation. The verified search results do not provide those values, so system-level compliance cannot be concluded from the product listing alone.
Рекомендуется
Industrial Networked Sensor
An industrial networked sensor may use the TPS2370DR when its power source is an IEEE 802.3af PoE port and the sensor includes the necessary Ethernet isolation and protection architecture. The part’s identified role as a PoE power interface switch makes it relevant to remote monitoring equipment, but the commercial temperature-grade description does not by itself establish suitability for every industrial environment. Confirm the operating temperature, electrical limits, fault response, and enclosure-related thermal conditions from the manufacturer datasheet before deployment.
Рекомендуется
Remote Telemetry Terminal
The TPS2370DR can be evaluated for remote telemetry equipment that receives power through an Ethernet connection rather than a local supply. IEEE 802.3af compatibility makes the device relevant to low-power network endpoints, but the actual design must reconcile the terminal’s operating mode, startup demand, cable losses, and downstream protection with the TPS2370’s verified ratings. The supplied data contains no confirmed current, voltage, or thermal specifications, so engineers should use the official product documentation and validate the complete PoE power budget before schematic capture.

Заметки по проектированию
Treat the TPS2370DR as part of a complete IEEE 802.3af PoE power path rather than as an isolated voltage regulator. Verify the downstream load, startup current, cable losses, protection behavior, and the manufacturer’s absolute maximum and recommended operating ratings before selecting nearby components. The verified source data does not provide current or voltage limits, so do not size inductors, magnetics, resistors, or thermal copper from inferred values.
Use the official TPS2370 datasheet land pattern and pin numbering when laying out the 8-SOIC footprint. Keep the power-path traces short and adequately wide for the actual current, and place protection, decoupling, and bypass components at the locations required by the application circuit. Because the supplied data does not provide verified pin functions or a public pinout, PCB release must wait for a direct datasheet cross-check.
Do not assume that any similarly described PoE switch is a drop-in replacement. TPS2377DR, TPS2375DR, TPS2062DR-1, TPS2051BDR, and TPS2419D appeared only as comparison candidates in the supplied search results; no verified pin compatibility or complete parameter match was established. Compare exact pin assignments, voltage/current ratings, protection behavior, package dimensions, and application requirements before approving a substitution.
Информация о соответствии
The supplied verified data does not provide compliance declarations for TPS2370DR. The commercial temperature-grade description does not establish AEC-Q100 qualification.
