(Note CONDITIONS Step TIMER Step Step Note 3: An internal Zener on the GATE pin clamps the charge pump voltage to a typical maximum voltage of 26V. External overdrive of the GATE pin beyond the internal Zener voltage may damage the device. Without a limiting resistor, the GATE capacitance must be < ...

... SENSE pins are strongly recommended. The CC drawing in Figure 1 illustrates the connections between the LTC4210 and the sense resistor. PCB layout should be balanced and symmetrical to minimize wiring errors. In addition, the PCB layout for the sense resistor should include good thermal management techniques for optimal sense resistor power dissipation ...

... When the card is being inserted into the bus connector, the long pins mate first which brings up the supply V point 1 of Figure 3. The LTC4210 is in reset mode as the ON pin is low. GATE is pulled low and the TIMER pin is pulled low with a 100 A source. At time point 2, the short pin makes contact and ON is pulled high ...

... LTC4210-1/LTC4210 APPLICATIO S I FOR ATIO The current through R can be divided into two SENSE components; I due to the total load capacitance CLOAD (C ) and I due to the noncapacitive load elements. LOAD LOAD The capacitive load typically dominates. For a successful start-up without current limit LIMIT < I RSENSE ...

... When the circuit breaker trips, the GATE pin is pulled low. The TIMER enters latchoff mode with pull-up for the LTC4210-2 (latched-off version), while an autoretry “cool- off” cycle begins with pull-down for the LTC4210-1 (autoretry version). An autoretry cool-off delay of the LTC4210-1 between COMP2 and COMP1 thresholds takes: ...

... C1, the TIMER pin pulls down with approximately a 7k resistor to ground and a GATE start-up cycle is initiated. If the fault persists, the fault autoretry duty cycle is approximately 3.8%. Pulling the ON pin low for more than 30 s will stop the autoretry function and put the LTC4210 in reset mode ...
