Data Sheet R03DS0091EJ0600 RNA52A10MM (Previous code: REJ03D0858-0500) Rev.6.00 Dual CMOS systemRESET IC Dec 19, 2014 Description The RNA52A10MM incorporates two reset circuits, one with and one without a delay function, allowing the generation of separate reset signals for a microprocessor and associated system circuits. The detection voltage of each reset circuit is determined by the value of an external resistor, and the internal reference voltage is 1.0 V. The CMOS process for the RNA52A10MM means that the device draws only 1.1 A (typ.). The reset cancellation delay time is set with a high degree of accuracy by the values of a capacitor and resistor connected with the CD pin. The MR (manual reset) input pin is provided for the reset circuit with the delay function, and the reset signal is output in response to a high level on the MR input pin. The MR pin is pulled down by a 2-M internal resistor. Output pins Vo1 and Vo2 are open drain. Features Two CMOS reset circuits, one with and one without the delay function Reference voltage: 1.0 V Reference voltage accuracy: 50 mV Reference voltage hysteresis: 6% (typ.) Low current consumption: 1.1 A (typ.) Delay time set by an external CR circuit Manual reset input Open-drain output MMPAK-8 (8-pin) package Operating temperature range: 40 to 85C Ordering Information Package Taping Abbreviation Part Name Package Type Package Code Abbreviation (Quantity) RNA52A10MMEL MMPAK-8 pin PLSP0008JC-A MM EL (3,000 pcs / Reel) Application Power-supply monitoring and resetting for microprocessors Power supply sequence control for microprocessors Desktop and laptop PCs PC peripheral devices such as printers Digital still cameras, digital video cameras, and PDAs Battery-driven products Wireless communications systems R03DS0091EJ0600 Rev.6.00 Page 1 of 11 Dec 19, 2014 RNA52A10MM Pin Arrangement MR 1 8 VDD Vo1 2 7 Vi1 Vo2 3 6 Vi2 GND 4 5 CD Outline and Article Indication RNA52A10MM Index band Marking R 0 1 Y : Year code (the last digit of year) M : Month code W : Week code Y M W MMPAK8 Lot No. R03DS0091EJ0600 Rev.6.00 Page 2 of 11 Dec 19, 2014
