A6130

EM MICROELECTRONIC-MARIN SA A6130 High Efficiency Linear Power Supply with Accurate Power Surveillance and Software Monitoring Features ■ Highly accurate 5 V, 100 mA guaranteed output ■ Low dropout voltage, typically 380 mV at 100 mA ■ Low quiescent current, typically 155 µA ■ Standby mode, maximum current 340 µA (with 100 µA load on OUTPUT) ■ Unregulated DC input can withstand -20 V reverse battery and +60 V power transients ■ Fully operational for unregulated DC input voltage up to 26 V and regulated output voltage down to 3.0 V ■ Reset output guaranteed for regulated output voltage down to 1.2 V ■ No reverse output current ■ Very low temperature coefficient for the regulated output ■ Current limiting ■ Comparator for voltage monitoring, voltage reference 1.17V ■ ±2.2% voltage reference accuracy at +25°C ■ ±4.2% voltage reference accuracy from -40 to +85°C ■ Programmable reset voltage monitoring ■ Programmable power on reset (POR) delay ■ Watchdog with programmable time windows guarantees a minimum time and a maximum time between software clearing of the watchdog ■ Time base accuracy ±10% ■ System enable output offers added security ■ TTL/CMOS compatible ■ -40 to +85°C temperature range ■ DIP8 and SO8 packages lated output voltage as low as 1.2 V. The watchdog function monitors software cycle time and execution. If software clears the watchdog too quickly (incorrect cycle time) or too slowly (incorrect execution) it will cause the system to be reset. The system enable o...
