R3115Z_E.doc/2003/05/06
NO. EA-098-0301
OUTLINE
The R3115Z Series are CMOS-based voltage detector ICs with high detector threshold accuracy and ultra-low sup-
ply current, which can be operated at an extremely low voltage and is used for system reset as an example.
Each of these ICs consists of a voltage reference unit, a comparator, resistor net for detector threshold setting, an
output driver, a hysteresis circuit, and an output delay circuit. The detector threshold is fixed with high accuracy inter-
nally and does not require any adjustment. Two output types, Nch open drain type and CMOS type are available.
Since the package is WL-CSP, high density mounting on boards is possible.

ABSOLUTE MAXIMUM RATINGS
Absolute Maximum ratings are threshold limit values that must not be exceeded ever for an instant under any condi-
tions. Moreover, such values for any two items must not be reached simultaneously. Operation above these absolute
maximum ratings may cause degradation or permanent damage to the device. These are stress ratings only and do
not necessarily imply functional operation below these limits.
Power Dissipation
Power dissipation depends on the condition of the mounting on board, the experiment result below is just an example.

of this IC is large, detector threshold level would shift by voltage dropdown caused by the consump-
tion current of the IC itself. Released voltage may also shift and delay time for start-up might be generated by this us-
age.
When R3115Zxx1C (CMOS Output Type) is used in Figure A or Figure B, Output level could be unstable by cross
conduction current which is generated at detector threshold level or at released voltage level, therefore, do not use
R3115Zxx1C with the connection in Figure A or Figure B.
The connection in Figure C may cause the oscillation in both R3115Zxx1C (CMOS Output) and R3115Zxx1A (Nch
Open Drain Output), therefore do not use R3115Zxx1x Series with the connection in Figure C.
