Hot Swap Power Manager for Redundant –48-V Supplies
Checkfor Samples: TPS2350
1FEATURES
DESCRIPTION• Replaces OR-ing Diodes The TPS2350 isa hot swap power manager
• Operating Supply Rangeof –12Vto –80V optimized for replacing OR-ing diodesin redundant
• Withstands Transientsto –100V power –48-V systems. The TPS2350 operates with
supply voltages from –12Vto –80V, and withstands
• Programmable Current Limitspikesto –100V.
• Programmable Linear Inrush Slew RateThe TPS2350 uses two power FETs as low voltage
• Programmable UV/OV Thresholds drop diodes to efficiently select between two
• Programmable UV and OV Hysteresis redundant power supplies. This minimizes system
• Fault Timerto Eliminate Nuisance Trips power dissipation and also minimizes voltage drop
through the power management chain.
• Power Good and Fault Outputs 14-Pin SOIC and TSSOP Package The TPS2350 also usesa third power FETto provide
load current slew rate control and peak current
limiting thatis programmed by one resistor and one
APPLICATIONScapacitor. The device also providesa power good
• –48-V Distributed Power Systems outputto enable down-stream power converters and
• Central Office Switching a fault outputto indicate load problems.
