... Industrial high-side switches/circuit breakers Electronic circuit breakers GENERAL DESCRIPTION The ADM4210 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 ...

... Input Pin. The ON (ON-CLR) pin is an input to a comparator that has a low-to-high threshold of 1.3 V with 80 mV hysteresis and a glitch filter. The ADM4210 is reset when the ON (ON-CLR) pin is low. When the ON (ON- CLR ) pin is high, the ADM4210 is enabled. A rising edge on this pin has the added function of clearing a fault and restarting the device on the latched off model, the ADM4210-2 ...

... The ADM4210 can reside either on the backplane or on the removable board. OVERVIEW The ADM4210 operates over a supply range the supply voltage is coming up, an undervoltage lockout circuit checks if sufficient supply voltage is present for proper operation. During this period, the FET is held off by the GATE pin being held to GND ...

... Pull-down Pull-down POWER-UP TIMING CYCLE The ADM4210 is in reset when the ON (ON- CLR ) pin is held low. The GATE pin is pulled low and the TIMER pin is pulled low with a 100 μA pull-down. At Time Point 2 in Figure 30, the ON (ON- CLR ) pin is pulled high. For the device to startup correctly, the supply voltage must be above UVLO, the ON (ON- CLR ) pin must be above 1 ...

... The period of this cycle is determined by the timer capacitor at a duty cycle of 3.8% on and 96.2% off. The ADM4210-2 model has a latch off system whereby when a current fault is detected, the GATE is switched off after a time determined by the timer capacitor (see Figure 33 for details). ...
