V6130

EM MICROELECTRONIC-MARIN SA V6130 Accurate Power Surveillance and Software Monitoring Features n Standby mode, maximum current 35 µA n Reset output guaranteed for VDD voltage down to n Comparator for voltage monitoring, voltage reference n ±1.5% voltage reference accuracy at +25 °C n Programmable reset voltage monitoring n Programmable power-on reset (POR) delay n Watchdog with programmable time window Typical Operating Configuration 1.2 V 1.17 V ±3% voltage reference accuracy for -40 to +85 °C n n n n n n guarantees a minimum time and a maximum time between software clearing of the watchdog Time base accuracy ±10% System enable (EN) output offers added security TTL/CMOS compatible -40 to +85 °C temperature range On request extended temperature range, -40 to +125 °C DIP8 and SO8 packages Description The V6130 offers a high level of integration by voltage monitoring and software monitoring in an 8 lead package. A comparator monitors the voltage applied at the VIN input comparing it with an internal 1.17 V reference. The power-on reset function is initialized after VIN reaches 1.17 V and takes the reset output inactive after TPOR depending of external resistance. The reset output goes active low when the VIN voltage is less than 1.17 V. The RES and EN outputs are guaranteed to be in a correct state for a supply voltage as low as 1.2 V. The watchdog function monitors software cycle time and execution. If the software clears the watchdog too quickly (incorrect cycle time...
