19-3263; Rev 1; 7/04 www.DataSheet4U.com Positive High-Voltage, Hot-Swap Controllers General Description The MAX5933A–MAX5933F/MAX5947A/B/C fully integrated hot-swap controllers for +9V to +80V positive supply rails (MAX5947A/B/C), allow for the safe insertion and removal of circuit cards into live backplanes without causing glitches on the backplane power-supply rail. The MAX5947B is pin- and function-compatible with the LT1641-2. The other devices offer added features such as a choice of act.

Positive High-Voltage Hot-Swap Controllers

19-3263; Rev 1; 7/04 www.DataSheet4U.com Positive High-Voltage, Hot-Swap Controllers General Description The MAX5933A–MAX5933F/MAX5947A/B/C fully integrated hot-swap controllers for +9V to +80V positive supply rails (MAX5947A/B/C), allow for the safe insertion and removal of circuit cards into live backplanes without causing glitches on the backplane power-supply rail. The MAX5947B is pin- and function-compatible with the LT1641-2. The other devices offer added features such as a choice of active-high or active-low power-good outputs (PWRGD/PWRGD), latched/autoretry fault management, and autoretry duty-cycle options of 3.75% or 0.94% (see the Selector Guide). The MAX5933A–MAX5933F are available with a default undervoltage lockout threshold of +31V and operate over a supply voltage range of +33V to +80V. The MAX5947A/B/C are available with a default undervoltage of +8.3V. All devices feature a programmable analog foldback current limit. If the device remains in current limit for more than a programmable time, the external n-channel MOSFET is either latched off (MAX5933A/ MAX5933C/MAX5947A) or is set to automatically restart after a timeout delay (MAX5933B/MAX5933D/MAX5933E/ MAX5933F/MAX5947B/MAX5947C). The MAX5933_ and MAX5947_ operate in the extended temperature range of -40°C to +85°C. These devices are available in an 8-pin SO package. Features ♦ Pin- and Function-Compatible with the LT1641-2 (MAX5947B) ♦ Provides Safe Hot Swap for +9V to +80V PowerSupply Range (MAX5947A.
