The ELECTRICAL CHARACTERISTICS
●
denotes the specifi cations which apply over the full operating temperature range, otherwise specifi cations are at TA = 25°C. VIN = 3.6V, VBAT = 3.6V, unless otherwise noted. PARAMETER CONDITIONS MIN TYP MAX UNITS
Schottky DP Forward Drop ISWP = 400mA 1045 mV Schottky DN Forward Drop ISWN = 600mA 980 mV Disconnect PNP VCE IVPOS = 50mA 205 mV Disconnect Current Limit VCAP = 15V, VPOS = 0V 100 155 mA VCAP – VBAT to Disconnect VBAT = 3.6V, VPOS = 0V, ICAP < 100µA 1.2 1.6 V Disconnect Leakage VBAT = 3.6V, CAP = 3.6V, VPOS = 0V 0.1 1.0 µA
Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
Guaranteed by design, not directly tested. may cause permanent damage to the device. Exposure to any Absolute
Note 4:
Current fl ows out of pin. Maximum Rating condition for extended periods may affect device
Note 5:
Current limit guaranteed by design and/or correlation to static test. reliability and lifetime. Slope compensation reduces current limit at higher duty cycle.
Note 2:
The LT3487E is guaranteed to meet specifi ed performance from 0°C to 85°C. Specifi cations over the –40°C to 85°C operating range are assured by design, characterization and correlation with statistical process controls.
