If CE input is low at the time power-fail detection occurs.
CE High to Power-Fail. Voltage on Any Pin Relative to Ground. Power-fail detection occurs in the. I CC02 is the maximum average load current which the DS can supply ds1120 the memories in the. All voltages are referenced to ground.
Measured with a load as shown in Figure 2. I CC01 is the maximum average load which the DS can supply to the memories. Tests Battery Condition on Power up. During battery backup operation the battery with datasheey highest.
A battery status warning will occur. This switch has a voltage drop of less than 0. DS is recognized by Underwriters Laboratory U. Datashedt for Redundant Batteries. First, a switch is provided to direct power from the battery or the incoming supply V CCI depending on. If the battery voltage is less than.
The nonvolatile controller contains circuitry to.
A grounded V BAT2 pin will not activate a battery-fail. The DS constantly monitors the incoming. In these applications it is often desirable to. The switch to a. The fourth function the DS Automatically Switches to Battery when. CEO will follow CE with a maximum propagation delay of 20ns. This is to maintain the battery s at its highest capacity until the equipment is. A subsequent write cycle can then be executed to the same datahseet location altering the data.

For industrial products Nthis range is ? Battery status can, therefore, be determined by. The DS controller provides an internal isolation switch which. When such a condition is detected, chip enable is inhibited to accomplish write protection and. DS 8-pin DIP mil. Unused battery inputs must be grounded. Incoming power is monitored for an out-of-tolerance.
Optional Industrial N Temperature Range of. All AC and DC electrical characteristics are valid for the full temperature range. This is a stress rating only and functional satasheet of the device at these or any other conditions.

The delay of write protection until. The fifth function of the nonvolatile controller provides for battery. Recovery at Power Up. Each time that the circuit is. When the supply goes out of tolerance a precision comparator detects power-fail and inhibits chip. CEO datashete only sustain leakage current in the battery backup mode. Only one battery input is required. The BAT2 battery pin must be grounded. C for N parts.
If one battery should fail, the other will take over the load. During nominal supply conditions. In applications where battery redundancy is not required, a single battery should be connected to.
The third function of write protection is accomplished by holding the CEO output signal to. The second function which the. In many applications, data integrity is paramount. Special circuitry uses a low. Figure 1 shows a typical application incorporating the DS in a microprocessor-based system.
