2 / 4 page GN809 Page: 2/4 ISSUED DATE :2006/08/18 REVISED DATE : Pin Description Pin Name Pin Description Gnd Ground RESETB RESETB is active low and push-pull output VIN Positive power supply. A reset is asserted after this voltage drops below a predetermined. After VIN rises above that level the reset output remains asserted until the end of the reset timeout period.
