... The start up current can be substantially reduced by limiting the slew rate at the gate of an N-channel as shown in Figure 1. The gate drive output of the LTC1981/LTC1982 have an internal 30k resistor (15k LTC1981) in series with each of the output gate drive pins (see Functional Block Diagram) ...

... APPLICATIONS www.DataSheet4U.com INFORMATION Reverse Battery Protection The LTC1981/LTC1982 can be protected against reverse battery conditions by connecting a 150 resistor in series with the supply pin as shown in Figure 4. The resistor limits the supply current to less than 24mA with –3.6V applied. Because the LTC1981/LTC1982 draw very little current while in normal operation, the drop across the resistor is minimal ...
