FIGURE 19. — LOW VOLTAGE MICROPROCESSOR RESET with ADDITIONAL HYSTERESIS Comparator hysteresis can be increased with the addition of resistor R H. The hysteresis equation has been simplified and does not account for the change of input current I IN as VCC crosses the comparator threshold. An increase of the lower threshold ∆V TH (LOWER) will be observed due to IIN which is typically 340µA at 4.59V. The equations are accurate to ±10% with R H less than 150Ω and RL between 1.5k Ω and 10kΩ. V H = + 0.02 ∆V TH (LOWER) = 340 RH x 10 -6 Where: R H ≤ 150Ω R L ≥ 1.5Ω ≤ 10kΩ 4.6 R H R L TEST DATA V H ∆V TH R H R L (mV) (mV) ( Ω)(Ω) 20 000 51 3.4101.5 40 6.8204.7 81 6.8201.5 71 10 30 2.7 112 10 30 1.5 100 16 47 2.7 164 16 47 1.5 190 34 100 2.7 327 34 100 1.5 276 51 150 2.7 480 51 150 1.5 FIGURE 20. — SOLAR POWERED BATTERY CHARGER 1.2 V REF MICROPROCESSOR CIRCUIT RESET V IN POWER SUPPLY R L R H I IN 1.2 V REF RESET V IN SOLAR CELLS PRODUCTION DATA - Information contained in this document is proprietary to LinFinity, and is current as of publication date.
