RD3ST24

RD3ST24 Standby Control IC REJ03D0521-0200 Rev.2.00 Mar 01, 2006 Description RD3ST24 is including the standby control circuit for a microcomputer in 8 pin packages. When MSTB input "Low", SWOUT output "Low", STBYOUT output become “High” and cancels standby condition. And RESOUT output becomes ''High'' after it passed period (t1*) when it is stable the oscillation that was set up with RC bill outside and cancel the reset condition of a microcomputer. Also when MSTB input "Low", RESOUT output becomes "Low" and makes reset condition. After the delay time (t2) of prescription passed subsequently, SWOUT output "High" STBYOUT output becomes "Low" and makes a microcomputer standby condition. *: t1 = KRC (K is coefficient: Reference of application data) Features Supply voltage range: 2.3 to 5.5 V Temperature range: –40 to +85°C Output current: ±6mA (@VCC=3.0V), ±12mA (@Vcc=4.5V) Ordering Information Part Name Package Type Package Code (Previous Code) RD3ST24USE SSOP-8 pin PVSP0008KA–A (TTP-8DBV) Package Abbreviation US Taping Abbreviation (Quantity) E (3,000 pcs/reel) Outline and Article Indication RD3ST24 Index band Lot No. SSOP-8 YMW S24 Y : Year code (the last digit of year) M : Month code W : Week code Marking Rev.2.00 Mar 01, 2006 page 1 of 9 RD3ST24 Pin Arrangement BATT 1 SWOUT 2 MSTB 3 GND 4 8 Vcc 7 RESOUT 6 STBYOUT 5 RxCx Pin Description BATT SWOUT MSTB GND RxCx STBYOUT RESOUT VCC Symbol Pin Name The battery power supply Output for Powe...
