6 _______________________________________________________________________________________
MAX5902L/MAX5903L turn off the MOSFET, discon-
necting the load immediately. If no circuit-breaker fault
exists, the MAX5902/MAX5903 assert the power-good
output. Then, if any of four conditions exist, the power-
good output deasserts and the MAX5902/MAX5903
turn off the MOSFET. The four conditions are: the volt-
age across the MOSFET exceeds the circuit-breaker
threshold; the supply voltage falls below the undervolt-
age lockout level; the die temperature exceeds
+125癈; or ON/OFF is forced low. After a circuit-break-
er fault, the MAX5902L/MAX5903L keep the MOSFET
off until the power is cycled, or the part is reset by tog-
gling ON/OFF low for 10ms (typ). After a circuit-breaker
fault, the MAX5902A/MAX5903A automatically restarts
in 150ms (typ). All versions automatically restart after a
thermal fault, or an undervoltage shutdown, if the fault
condition goes away for at least 150ms (typ).
ON/OFF offers external control of the MAX5902/
MAX5903, facilitating power-supply sequencing, and
may also be used to change the undervoltage lockout
(UVL) level. UVLO keeps the external MOSFET
switched off as long as the input voltage is below the
desired level.
A power-good output, PGOOD (MAX5902) or PGOOD
(MAX5903), asserts when the external MOSFET is fully
enhanced and the source-drain voltage is below the
circuit-breaker threshold. PGOOD and PGOOD are
open-drain outputs referenced to GND, and can with-
stand up to +72V.
