PD69101 Datasheet | Microchip Technology

features . - Designed to detect and disable disconnected ports, utilizing DC disconnection methods as specified in the AF and IEEE802.3 af/at standards. - Low-power device using an internal 0.34Ω MOSFET and an external 0.5Ω sense resistor. - Optionally detects legacy/pre-standard PD devices. - Provides overload, underload, overvoltage, overtemperature, and short-circuiting PD protection. - Supports supply voltages ranging from 32V to 57 VDC with no need for additional power supply sources. © 2021 Microchip Technology Inc. and its subsidiaries DS00004280A-page 1 Features The PD69101 device has the following key features . - Fully AF and AT pliant - Includes two-event classification - Supports pre-standard PD detection - Single DC voltage input (32V- 57 VDC) - Supports 2-pairs - VMAIN out-of-range protection - Wide temperature range: - 40°C to 85°C - Overtemperature protection - Low thermal dissipation (0.5Ω sense resistor) - Includes on/off mand pin - 2× direct LEDs drive - Continuous port monitoring and system data - Configurable load current setting - Configurable AT/AF modes - Configurable standard and legacy detection mode - Power soft-start mechanism - On-chip thermal protection - Voltage monitoring and protection - Built-in 3.3 VDC regulator - Internal power-on-reset - Ro HS pliant - Low Rdson FET: 0.3Ω - MSL3 © 2021 Microchip Technology Inc. and its subsidiaries DS00004280A-page 2 Typical 2-Pair Application The following figure shows a typical application of simple plug-and-play Po E solution for a single Ethernet port switch or hub. POS and NEG signals must be connected to the switch RJ45 jack. AF and AT modes of operations are set through AF/AT and current-set pins (DGND or DVDD). Figure 1. Typical 2-Pair...
