The ADM1172 is a hot swap controller that safely enables a printed circuit board to be removed and inserted to a live backplane. This is achieved using an external N-channel power MOSFET with a current control loop that monitors the load current through a sense resistor. An internal charge pump is used to enhance the gate of the N-channel FET. When an overcurrent condition is detected, the gate voltage of the FET is reduced to limit the current flowing through the sense resistor. During an overcurrent condition, the TIMER pin capacitor determines the amount of time the FET remains at a current limiting mode of operation until it is shut down. The ON (ON-CLR) pin is the enable input for the device and can be used to monitor the input supply voltage. The ADM1172 operates with a supply voltage ranging from 2.7 V to 16.5 V.The ADM1172 also features a power-fail comparator. The voltage on the PFI pin is compared with an internal 0.6 V reference, and the output of this comparator is presented on the PFO pin. This device is available in two options: the ADM1172-1 with automatic retry for overcurrent fault and the ADM1172-2 with latch-off for an overcurrent fault. Toggling the ON (ON-CLR) pin resets a latched fault. The ADM1172 is packaged in an 8-lead TSOT.Applications Hot swap board insertion: line cards, raid systems Industrial high-side switches/circuit breakers Electronic circuit breakers

The ADM13305 is a dual voltage supervisor designed to monitor two supplies and provide a reset signal to DSP and microprocessor-based systems.There are five models available, all of which feature a combination of internally pretrimmed undervoltage threshold options for monitoring 1.8 V, 2.5 V, 3.3 V, and 5 V supplies. There is also an adjustable input option with an undervoltage threshold voltage of 0.6 V.The ADM13305-18, ADM13305-25, and ADM13305-33 models have two internally fixed thresholds. The ADM13305-4 and ADM13305-5 offer one internally fixed threshold and one externally programmable threshold via a resistor string. See the Ordering Guide for a list of all available options.During power-up, RESETis asserted when the supply voltage exceeds 1.1 V. The device then monitors the SENSEv input pins and holds the RESET output low as long as either of the SENSEv inputs remains below the rising threshold voltage, VIT+.Once the supplies monitored at the SENSEv inputs rise above their associated thresholds, the reset signal remains low for the reset timeout period before deasserting. Subsequently, if a voltage monitored by the SENSEv pins falls below its associated falling threshold, VIT−, RESET the output asserts. The ADM13305 features both an active high RESET and an active low RESET output.As well as providing power-on reset signals, an on-chip watchdog timer can reset the microprocessor if it fails to strobe within the preset timeout period. A reset signal can also be asserted by an external push button through the manual reset input pin.The ADM13305 is available in an 8-lead, narrow body SOIC package. The device operates over the extended industrial temperature range of −40°C to +85°C.APPLICATIONS Supervising DSPs/microcontrollers Industrial and portable equipment Wireless systems Notebook/desktop computers
