6 / 9 page ( / 9 ) ELECTRIC MITSUBISHI M62021L,P,FP MITSUBISHI<Dig.Ana.INTERFACE> SYSTEM RESET IC WITH SWITCH FOR MEMORY BACK-UP 6 Input voltage Output pin In normal operation VOUT RES RES CS In failure(instantaneous drop) Input voltage:5V With Q4 set to ON, a voltage (VIN-VDROP)is output The output level is VOL(RES) with a logic low The output level is VOH(RES) with a logic low The output level is VOL(CS) with a logic low Input voltage:5V 4V Each output varies if the input voltage drops to VSL or under Q4 is turned OFF.A voltage (VIN-Q4 VEB(Di) is output by the diode between E and B of Q4 As the state shifts from a logic low to logic high,the output level becomes approximately equal to the input voltage As the state shifts from a logic high to logic low,the output level becomes VOL(RES) As the state shifts from a logic low to logic high,the output level becomes the voltage VIN- Q4EB(Di). Restoration from failure (instantaneous drop) Input voltage:4V 5V If the input voltage goes higher than VSL by 100mV,each out-put varies after delay produced by the delay circuit Q4 is turned ON after delay and a voltage(VIN-VDROP) is output A logic high is maintained,and than shifts to a logic high A logic low is held,and than shifts to a logic high A logic high is maintained,and than shifts to a logic high In backup state Input voltage:0V Backup voltage:3V VBAT-VF The output is a logic high and the output level is VBAT-VF TIMING CHART VIN 0V VOUT RES RES tpd tpd 5V CS ∆Vs VSH VSL V1 V2 V3 V4 V5 V2 V5 V4 VOL(CS) 5V VIN(VSL) VOL(RES) VOL(RES) VIN(VSL) VOL(RES) V1=VIN-VDROP V2=VIN-Q4VEB(Di) V3=VIN(VSL)-VDROP V4=VIN(VSL)-Q4VEB(Di) V5=VBAT-VF |
