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 = K•RC (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) Package Abbreviation Taping Abbreviation (Quantity) RD3ST24USE SSOP-8 pin PVSP0008KA–A (TTP-8DBV) US E (3,000 pcs/reel) Outline and Article Indication • RD3ST24 Index band Lot No. Y M W S 2 4 SSOP-8 Marking Rev.2.00 Mar 01, 2006 page 1 of 9 Y : Year code (the last digit of year) M : Month code W : Week code RD3ST24 Pin Arrangement BATT 1 8 Vcc SWOUT 2 7 RESOUT MSTB 3 6 STBYOUT GND 4 5 RxCx Pin Description Symbol Pin Name BATT SWOUT MSTB GND RxCx STBYOUT The battery power supply Output for Power MOS FET control Manual standby Input Ground Terminal for external resistance and capacitance Standby Output RESOUT VCC Reset Output Power supply Rev.2.00 Mar 01, 2006 page 2 of 9 RD3ST24 Absolute Maximum Ratings Item Supply voltage range Symbol VCC Ratings –0.5 to 7.0 Unit V Input voltage range *1 Output voltage range *1, 2 VI VO V V Input clamp current Output clamp current Continuous output current IIK IOK IO ICC or IGND –0.5 to VCC + 0.5 –0.5 to VCC + 0.5 –0.5 to 7.0 ±20 ±50 ±25 ±50 mA mA mA mA PT 200 mW Tstg –65 to 150 °C Continuous current through VCC or GND Maximum power dissipation 3 at Ta = 25°C (in still air) * Storage temperature Test Conditions Output: H or L VCC: OFF VI < 0 VO < 0 or VO > VCC VO = 0 to VCC Notes: The absolute maximum ratings are values, which must not individually be exceeded, and furthermore no two of which may be realized at the same time. 1. The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. This value is limited to 6.0 V maximum. 3. The maximum package power dissipation was calculated using a junction temperature of 150°C.
