Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

‌LTC4292IUJ is a 4-port Power Supply device (PSE) controller for Power over Ethernet (PoE) systems that comply with IEEE 802.3bt Class 3 and Class 4 standards ‌‌. The LTC4292IUJ chipset achieves low heat dissipation in the industry by utilizing low RDS(ON) external MOSFETs and 0.15Ω detection resistors per power channel. It also replaces expensive photocouplers and complex isolated 3.3V power supplies with transformer-isolated communication protocols, resulting in significant savings in BOM costs ‌.

The LTC4292IUJ has the following features:

Four PSE ports

Each port has two power channels

PSE fully compliant with IEEE 802.3bt Class 3 and Class 4 standards

Compliance support for Category 1, 2, 3 and 4 PDS

Low power path loss per channel

150mΩ induction resistance

30 Mω or less MOSFET RDS(ON)

The chipset provides electrical isolation

Photoelectric components and isolated 3.3V power supplies are no longer required

Extremely reliable multi-point PD detection

Connection checks can distinguish between single-signed and double-signed PD

Continuous, dedicated per-port power and current monitoring

Power monitoring for each port

Serial control interface compatible with 1MHz I2C

Up to 71.3W pin or I2C programmable PD power supply

Available in a 40-pin 6mm × 6mm QFN package

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?
