DESCRIPTION
Reset and data save functions and remote switch on/off control can be realized. PIN CONNECTION June 2000 1/9 L4902A PIN FUNCTIONS N° 1 2 3 4 5 Name Input 1 Timing Capacitor Disable Input GND Reset Output Regulators Common Input If Reg. 2 is switched-ON the delay capacitor is charged with a 5µA constant current. When Reg. 2 is switched-OFF the delay capacitor is discharged. A high level (> VDT) disable output Reg. 2. Common Ground When pin 2 reaches 5V the reset output is switched high. 5V ) ; tRD (ms) = Ct (nF) Therefore tRD = Ct ( 10µA 5V – 300mA Regulator Output. Enabled if Vo 1 > VRT.
