ILC5142

Impala Linear Corporation ILC5140/5141/5142 Advance CMOS Multilevel Voltage Detector General Description The ILC514X is an innovative, multilevel voltage detector, designed to monitor the terminal voltage of a power source and provide up to four independent flags when the voltage levels drop below designated levels. The ILC514X is unique in its design because one device can now signal the user when a discharging battery goes below four (4) different threshold voltages and because it requires no external precision components to monitor these voltage levels. The open drain flags are asserted when the terminal voltage goes below their designated thresholds and are de-asserted 140ms after the thresholds are exceeded. Additionally, the ILC514X has a manual reset pin that allows the system to assert all flags for a minimum of 200ms. Features Four levels of a single terminal voltage monitored No precision external components < 10µA Quiescent current Available in three outpu...
