TPS2379
- IEEE 802.3at Type-2 Hardware Classification With
Status Flag - Auxiliary Gate Driver for High-Power Expansion
- Robust 100-V, 0.5-Ω Hotswap MOSFET
- 1A (Typical) Operating Current Limit
- 140 mA (Typical) Inrush Current Limit
- DC-DC Converter Enable
- 15 kV/8 kV System-level ESD Capability
- PowerPAD™ HSOP Package
The TPS2379 device is an 8-pin integrated circuit that contains all of the features needed to implement an IEEE802.3at type-2 powered device (PD) such as Detection, Classification, Type 2 Hardware Classification, and 140-mA inrush current limit during startup. The low 0.5-Ω internal switch resistance, combined with the enhanced thermal dissipation of the PowerPAD package, enables this controller to continuously handle up to 0.85 A. The TPS2379 integrates a low 0.5-Ω internal switch to allow for up to 0.85 A of continuous current through the PD during normal operation. The TPS2379 device supports higher-power applications through an external pass transistor. The TPS2379 contains several protection features such as thermal shutdown, current limit foldback, and a robust 100-V internal switch.
