I. Device Description
The MAX5961 0 to 16V, quad, hot-swap controller provides complete protection for systems with up to four distinct supply voltages. The device allows
the safe insertion and removal of circuit cards into live backplanes. The MAX5961 is an advanced hot-swap controller that monitors voltage and
current with an internal 10-bit ADC. The device provides two levels of overcurrent circuit-breaker protection; a fast-trip threshold for a fast turn-off, and
a lower slow-trip threshold for a delayed turn-off. The maximum overcurrent circuit-breaker threshold range is set independently for each channel with
a trilevel input (ILIM_) or by programming though an I²C interface. The internal 10-bit ADC is multiplexed to monitor the output voltage and current of
each hot-swap channel. The total time to cycle through all the eight measurements is 100µs (typ). Each 10-bit value is stored in an internal circular
buffer so that 50 past samples of each signal can be read back through the I²C interface at any time or after a fault condition. The MAX5961 can be
configured as four independent hot-swap controllers, hot-swap controllers operating in pairs, or as a group of four hot-swap controllers. The device
also includes five digital comparators per hot-swap channel to implement overcurrent warning, two levels of overvoltage detection, and two levels of
undervoltage detection. The limits for overcurrent, overvoltage, and undervoltage are user-programmable. When any of the measured values violates
the programmable limits, an external active-low ALERT signal is asserted. In addition to the active-low ALERT signal, depending on the selected
operating mode, the MAX5961 can deassert a power-good signal and/or turn-off the external MOSFET. The MAX5961 is available in a 48-pin thin
QFN package and operates over the -40°C to +85°C extended temperature range.
