Key Features
- IEEE 802.3at (PoE+) and 802.3bt compliant PD controller enabling up to 90 W power delivery over standard Ethernet cabling
- Adjustable threshold inputs and 3 analog channels for flexible power budget management and multi-port sensing in PoE-powered equipment
- 45-pin VQFN (7 x 5 mm) package with integrated gate driver reducing external component count in compact PoE powered device designs
Applications
TPS23730RMTT is used in IEEE 802.3at and 802.3bt Powered Device (PD) designs such as IP cameras, wireless access points, VoIP phones, and smart building sensors that draw power directly from Ethernet cabling up to 90 W. Its adjustable thresholds and 3 analog inputs support flexible classification and power management across different PoE budget allocations from PSE switches. The compact VQFN-45 package simplifies PCB layout in space-constrained wall-mount or ceiling-mount network equipment enclosures.

Frequently Asked Questions
Which PoE standards does TPS23730RMTT support and what is the maximum power it can receive?
TPS23730RMTT supports IEEE 802.3at (PoE+, up to 30 W at the PD) and IEEE 802.3bt (up to 90 W at the PD) standards. It performs the required classification handshake with the PSE switch over the Ethernet pairs and can negotiate Type 3 or Type 4 power classes defined in 802.3bt, enabling high-power applications such as PTZ cameras, displays, and industrial IoT gateways on standard Cat5e or Cat6 cabling.
How do the adjustable threshold inputs on TPS23730RMTT assist in multi-port PoE system design?
TPS23730RMTT provides adjustable UVLO, OVLO, and current threshold inputs through external resistor dividers, allowing designers to configure the device for different input voltage windows (typically 36 V to 57 V) and inrush current limits without changing firmware. In a multi-port PoE system with varying PSE supply voltages, each port controller can be individually tuned by resistor selection, preventing nuisance disconnects on ports experiencing marginal cable voltages at 10 Ω to 15 Ω loop resistance.
Can TPS23730RMTT directly interface with an isolated DC/DC converter stage in a PoE camera design?
Yes. TPS23730RMTT integrates a gate driver output compatible with external N-channel MOSFETs used in the primary switch of an isolated flyback or forward converter. The PD controller handles the 802.3bt classification and turn-on sequence, then enables the converter switch gate at regulated 10 V drive. This allows a clean partition between the PoE PD interface and the isolated 12 V or 5 V power converter, with no additional gate driver IC required.
What package dimensions and thermal properties does TPS23730RMTT offer for compact PoE endpoint PCB layouts?
TPS23730RMTT uses a 45-pin VQFN package measuring 7 x 5 mm with an exposed thermal pad. The low-profile QFN format occupies 35 mm² of PCB area, significantly smaller than equivalent SOIC or TSSOP alternatives. The exposed pad provides a low-resistance thermal path to a copper pour, keeping junction temperature below 125°C at typical 802.3at 30 W dissipation levels with standard 2-layer PCB copper pours of 50 mm² to 100 mm².
