3 / 16 page Data Sheet ADP1614 Rev. 0 | Page 3 of 16 SPECIFICATIONS VIN = 3.6 V, unless otherwise noted. Minimum and maximum values are guaranteed for TJ = −40°C to +125°C. Typical values specified are at TJ = 25°C. All limits at temperature extremes are guaranteed by correlation and characterization using standard statistical quality control (SQC), unless otherwise noted. Table 1.

For the adjustable current limit versions, it is also a function of the resistor on the CLRES pin. See Figure 9 through Figure 12. 3 Guaranteed by design. 4 The CLRES pin cannot be controlled with a current source. An equivalent resistance should be used. |
