File Size : 116 KB Manufacturer:MOT Description:Thresholds and Outputs The H6061 has open-drain outputs and voltage thresholds on pin VIN of typically 1.5 V. Internal Voltage Comparators The voltage comparators detect the voltage applied to pin VIN and compare it with thresholds VSH, VSL and VRL. The H6061 is designed for monitoring regulated DC voltages and has bandgap thresholds independent of VDD. The reaction of the H6061 to voltage changes on pin VIN is given in Fig. 4. During powering-up, the outputs are active. After VIN reaches the VSH level, pin SAVE deactivates after a short debounce time TDB to allow for fast ramp-ups. The initialization time TTO then passes before the two reset outputs go inactive. Thereafter, when the voltage on pin VIN falls below the VSL level, pin SAVE goes active low as a first warning. If VIN then drops below the VRL level, the reset signals go active and are guaranteed down to 1.6 V. The reset outputs react also to timeouts (see Timer clearing). Note that when the supply voltage VDD is below the level VOFF (about 2.2 V), all outputs are in the active state for any allowed voltage of VIN. Voltage Programming The H6061 was designed to give the best compromise in normal usage (see Table 3). Its voltage threshold can be programmed by an external resistor divider or a potentiometer to react at proportionally higher voltage levels (see Fig. 8 below). Voltage Programming
