p6/13 rev. h, august 2009 ml61 functional description (refers to cmos output) 1. firstly, when a voltage, higher than the release voltage (v dr ) , is applied to the voltage input pin (v in ), that voltage will gradually fall. when a voltage higher than the detect voltage (v df ) is applied to the input voltage pin (v in ), output at v out will be equal to the input at the v in pin. high impedance exists on the output pin (v out ) with the n-channel open drain configuration. if the pin is pulled-up. v out will be identical to the pull-up voltage. 2. when the input voltage (v in ) falls below the detect voltage (v df ) level, the output voltage (v out ) is equal to the ground voltage (v ss ) level (detect state). also applicable to n-channel open drain configuration. 3. when the input voltage (v in ) falls below the minimum operating voltage (v min ) level, output becomes unstable. in the case of n-channel open drain configuration, as the output pin is generally pulled-up, the output will be equal to the pull-up voltage. 4. when the input voltage (v in ) rises, output become stable once the voltage has exceeded v min . the output voltage (v out ) will remain equal to the ground voltage (v ss ) level until the input voltage (v in ) reaches the detect release voltage (v dr ) level. 5. when the input voltage (v in ) rises above the detect release voltage (v dr ) level, output at the output pin (v out ) is equal to v in . (high impedance exists with the n-channel open drain output configuration and v out follows the pull-up voltage.) notes : 1. the difference between v dr and v df represents the hysteresis range. 2. the propagation delay time (t dly ) represents the time it takes for the input voltage (v in ) to appear at the output pin (v out ), once the said voltage has exceeded the release voltage (v dr ) level. timing diagram
