DS1260 Datasheet Smart Battery

Manufacturer: Dallas Semiconducotr

Overview: DS1260 Smart Battery www.dalsemi.com.

General Description

Pins 1, 2, 4, 7, 9, 10 and 14 are No-Connects Pin 3 is Battery Fail ( BF ) Pin 5 is Battery Out (BAT) Pin 6 is RESET (RST) Input Pin 8 is Ground Pin 11 is Power Fail ( PF ) Pins 12 and 13 are RAM Supply (VCCO) Pins 15 and 16 are +5V Supply (VCCI) DESCRIPTION The DS1260 SmartBattery is a low-cost, backup energy supply for portable and nonvolatile electronic equipment.

A lithium energy source of up to 1 amp hour can supply power to CMOS electronic circuits when primary power is lost through an intelligent and efficient switch.

When power is supplied from the lithium power source, the power fail signal is held low to warn electronic (RESET) circuits of the power status.

Key Features

  • Encapsulated lithium energy cell with shelf life beyond 10 years Available with energy capacities of 250, 500, and 1,000 mAH @ 3 volts Plugs into a standard 16-pin DIP socket Lithium cell electrically disconnects from exposed pins upon command Battery isolation ensures full capacity after shipping and handling Lithium cell automatically reconnects when VCC is applied Recessed pins prevent bending VCC fail signal interrupts processor or writeprotects memory Exhausted energy cell warning signal Lo.
