MAX5947AESA-Positive High-Voltage Hot-Swap Controller
The fully integrated MAX5933A-MAX5933F/MAX5947A/B/C +9 V to +80 V positive hot-swap controller rails (MAX5947A/B/C) can be safely inserted and relocated to a live backplane without Can cause circuit card glitches on the backplane power rails. "The MAX5947B is pin and functionally compatible with the LT1641-2. Other devices provide complementary features such as selection of an active-high or active-low power-good output (PWRGD/PWRGD), latching/auto-retry fault management, auto-retry Try a duty cycle of 3.75% or 0.94% equity (see the Selection Guide). The MAX5933A-MAX5933F offer a default undervoltage lockout threshold of 31 V, operating on a +33 V supply voltage range of 80 V. "The MAX5947A/B/C default undervoltage at 8.3 V. All devices feature a programmable analog foldback current limit. If the device remains in the current limit for a programmable amount of time, the external N-channel MOSFET is latched off (MAX5933A/MAX5933C/MAX5947A) or set to automatically restart after a timeout delay (MAX5933B/MAX5933D/MAX5933E/MAX5933F/MAX5947B/MAX5947C ). The MAX5933_ and MAX5947_ operate over the extended temperature range of -40°C to +85°C. These devices are available in an 8-pin SO package.
