Product Overview
The MAX5940BESA+ is an IEEE 802.3af PD interface controller for power over Ethernet in 8 pin NSOIC package. It provide PD with a detection signature, a classification signature and an integrated isolation switch with programmable inrush current control. Device also feature power mode undervoltage lockout (UVLO) with wide hysteresis and power good outputs. An integrated MOSFET provides PD isolation during detection and classification. A leakage current offset of less than 10µA during detection phase. A programmable current limit prevents high inrush current during power-on. The device features power mode UVLO with wide hysteresis and long deglitch time to compensate for twisted-pair cable resistive drop and to assure glitch-free transition between detection, classification and power-on/-off phases. It is used in IP phones, wireless access nodes, computer telephony and IEEE 802.3af power devices.
- Operating supply voltage of 67V (max), operating supply current of 1mA (max)
- Operating temperature range from -40°C to 85°C
- Less than 10µA leakage current offset during detection
- Integrated MOSFET for isolation and inrush current limiting
- Wide UVLO hysteresis accommodates twisted pair cable voltage drop
- PGOOD/PGOOD(complementary) outputs to enable downstream DC-DC converters
Applications
Power Management, Portable Devices, Consumer Electronics, Wireless, Security
