SPECIFICATIONS

VIN = 3.6 V, TA = 25°C for typical specifications, and TA = TJ = −40°C to +85°C for minimum and maximum specifications, unless

otherwise noted. All specifications at temperature extremes are guaranteed via correlation using the standard statistical quality control

(SQC) methods. Typical specifications are not guaranteed.
