Description
Product Overview
DC981A/B is a demonstration circuits 981A and 981B feature the LTC®4263 in single port Power over Ethernet (PoE) power sourcing equipment (PSE) midspan and endpoint solutions. The LTC4263 is an autonomous single-channel PSE controller for use in IEEE802.3af compliant PoE systems. It includes an onboard planar power MOSFET, internal inrush, current limit, and short-circuit control, powered device (PD) detection and classification circuitry, and selectable AC or DC disconnect sensing. Onboard control algorithms provide complete PSE control operation without the need of a microcontroller. The LTC4263 simplifies PSE implementation, needing only a single 48V supply and a small number of passive support components. Other options shown on DC981A include legacy PD detection enable, midspan backoff timer enable, power class enforce mode, and power management enable. An LED for each port is driven by respective LTC4263 to indicate state of the port. The DC981A is Ethernet Alliance� certified.
- 46V to 57V supply voltage at TA = 25°C (voltage for IEEE802.3af compliance at port output)
- 3.2s midspan mode detection backoff
- 17Kohm to 29.7Kohm detection range
- 17W set maximum allocated power at power management enabled, RPM = 12.4Kohm
