功能概述 HT70XX 系列带有高稳定的参考电压参考。它与比较器负输入端相连。见下图中NMOS 输出电压检测器的 VREF 。 当比较器正向输入（如VB）电压高于VREF 时，VOUT 置高，M1关闭，VBH=VDD×（RB+RC）/（RA+RB+RC）。如 果VDD 减少VB 降到少于VREF，比较器的输出从高变到低，VOUT 置低 VC 为高，M1 打开，RC 为旁路，VBL=VDD ×RB/（RA+RB），少于VBH 这样，当VB≈VREF 时比较器的输出为低防止电路产生振荡。 如果VDD 降到低于最小运行电压， 输出变为不确定。当VDD 从低变为VDD ×RB/ （ RA+RB ）> VREF 时， 比较器的输出和VOUT 都置高。 可检测电压表示为： VDET（-） = （RA+RB+RC） / （RB+RC ）× VREF 释放电压表示为： VDET （+） =

The hysteresis width is: VHYS = VDET (+) - VDET (-) The figure demonstrates the NMOS output type with positive output polarity (VOUT is normally open, active low). The HT70XXA-1 series also supplies options for other output types with active high outputs. Application circuits shown are examples of positive output polarity (normally open, active low) unless otherwise specified. When the voltage drop to the positive input of the comparator (i,e,VB) is higher than VREF, VOUT goes high, M1 turns off, and VB is expressed as VBH=VDD ´ (RB+RC) / (RA+RB+RC). If VDD is decreased so that VB falls to a value less than VREF, the comparator output inverts from high to low, VOUT goes low, VC is high, M1 turns on, RC is bypassed, and VB becomes: VBL= VDD ´ RB / (RA+RB), which is less than VBH. By so doing, the comparator output will stay low to prevent the circuit from oscillating when VB » VREF.
