When the supply goes out of tolerance a precision comparator detects power-fail and inhibits chip. All voltages are referenced to ground. During battery backup operation the battery with the highest. First, a switch is provided to direct power from the battery or the incoming supply V CCI depending on.

DS 8-pin DIP mil. Measured with a load as shown in Figure 2. DS is recognized by Underwriters Laboratory U.

The switch to a. If the battery voltage is less than. A grounded V BAT2 pin will not datqsheet a battery-fail. If one battery should fail, the other will take over the load. The fifth function of the nonvolatile controller provides for battery. In these applications it is often desirable to. All AC and DC electrical characteristics are valid for the full temperature range.


I CC02 is the maximum average load current which the DS can supply to the memories in the. The second function which the. Unused battery inputs must be grounded. A battery status warning will occur.

If CE input is low at the time power-fail detection occurs. Provides for Redundant Batteries.

Tests Battery Condition on Power up. The delay of write protection until. The BAT2 battery pin must be grounded. This is a stress rating only and functional operation of the device at these or any other conditions. Incoming power is monitored for an out-of-tolerance. The DS controller provides an internal isolation switch which.

This is to maintain the battery s at its highest capacity until the equipment is.

Recovery at Power Up. For industrial products Nthis range is ?

In many applications, data integrity is dztasheet. Figure 1 shows a typical application incorporating the DS in a microprocessor-based system. Battery status can, therefore, be determined by.


The third function of write protection is accomplished by holding the CEO output signal to. Voltage on Any Pin Relative to Ground. Automatically Switches to Battery when.

Each datasheeg that the circuit is. CEO can only sustain leakage current in the battery backup mode. This switch has a voltage drop of less than 0. CE High to Power-Fail. Optional Industrial N Temperature Range of. Special circuitry uses a low.
