Описание

The LTC4417IGN#PBF is a Prioritized PowerPath™ Controller that connects one of three valid power supplies to a common output based on priority. Priority is defined by pin assignment, with V1 assigned the highest priority and V3 the lowest priority. A power supply is defined as valid when its voltage has been within its overvoltage (OV) and undervoltage (UV) window continuously for at least 256ms. If the highest priority valid input falls out of the OV/UV window, the channel is immediately disconnected and the next highest priority valid input is connected to the common output. Two or more LTC4417s can be cascaded to provide switchover between more than three inputs. The gate driver includes a 6V clamp to protect external MOSFETs. A controlled output ramp feature minimizes start-up inrush current. Open drain VALID outputs indicate the input supplies have been within their OV/UV window for 256ms.

• Blocks reverse and cross conduction currents
• -42V Protection against reverse battery connection
• Fast switchover minimizes output voltage droop
• Low 28µA Operating current
• <1µA Current draw from supplies less than VOUT
• 1.5% Input overvoltage/undervoltage protection
• Adjustable overvoltage/undervoltage hysteresis
• P-channel MOSFET gate protection clamp
• Cascadable for additional input supplies
