The TPS3806 integrates two independent battery voltage monitoring voltage detectors. The power-on reset \ and RSTSENSE \ are asserted when the supply voltage V_DDOr the input voltage LSENSE becomes higher than 0.8 five, after which the supervisory circuit monitors_VDD and LSENSE, keep reset\ and RSTSENSE \ as active for the long term_VDD and LSENSE are still below the threshold voltage_Vway. while_VDD OR LSENSE RSTSENSE RISES ABOVE THE THRESHOLD VOLTAGE_VThe way to reset\ or \set as invalid, respectively. The TPS3806 device has a fixed threshold voltage_VEnter the guardrail, in V_DDand a second LSENSE with adjustable internal voltage. In addition, the high voltage threshold can be set to an adjustable hysteresis window within the allowable range of HSENSE.
