Product Overview
LTC4421HUHE#PBF is a high-power prioritized PowerPath controller. It connects one of two input supplies to a common output based on user-defined priority and validity. By definition, the supply connected to V1 is the higher-priority supply, although this can be changed dynamically. External resistive dividers set the undervoltage and overvoltage thresholds that bound the valid voltage window. Strong gate drivers switch the large external N-channel MOSFET quickly. Fast switchover circuitry minimizes output droop when changing channels while preventing reverse and cross-conduction. A fast comparator detects input short circuits and quickly turns off the N-channel MOSFETs to minimize disruption. Applications include high-reliability systems, server-based backup systems, industrial handheld instruments, and battery backup systems.
- V1, V2 operating voltage range from 3.0 to 36V
- Drives large external N-channel MOSFETs for high output current applications
- Accurately limits inrush current, connects highest priority valid supply to output load
- Changes channel priority in real time, ±2% OV, UV input comparators
- Individually adjustable current limit time-out for each channel
- Adjustable input validation time, fast switchover minimizes VOUT droop
- INTVCC output voltage range from 3.3 to 4.5V (IINTVCC = 0µA)
- Total input supply current is 0.53mA typ (V1, V2, OUT1, OUT2, EXTVCC, CPOREF)
- Rising threshold voltage range from 0.5 to 1.5V
- 36 lead plastic QFN package, operating ambient temperature range from -40°C to 125°C
