Samsung KA2411
the KA2411 allows connection of an external resistor RSL, which is used to program the slope of the supply current vs supply voltage characteristics (see Fig. This initial voltage remains constant independent of RSL. The supply current drawn prior to triggering varies inversely with RSL, decreasing for an increasing value of resistance.| Part No. | KA2411 |
