Exposure to absolute maximum rating conditions for extended periods of time may affect reliability. VIN, VOUT, LED1, LED2, LED3.......................... -0.3V to 6.0V SCL, SDA, RDY, RESET_N, CAP ............-0.3V to VIN +0.3V C1P, C2P, C1N, C2N ...........................-0.3V to VIN +0.3V Storage Temperature .............................. -65°C to 150°C Power Dissipation ................... Internally Limited (Note 1) Lead Temperature (Soldering, 10 sec) ................... 260°C ESD Rating (HBM - Human Body Model) All Pins ......... 2KV OPERATING RATINGS Input Voltage Range VIN...............................2.7V to 5.5V Junction Temperature Range ....................-40°C to 125°C Thermal Resistance θJA ................................... 30.8°C/W ELECTRICAL SPECIFICATIONS Specifications with standard type are for TJ = 25°C only; limits in applying over the full Operating Junction Temperature (TJ) range are denoted by a “•”. Minimum and Maximum limits are guaranteed through test, design, or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only. Unless otherwise indicated, VIN = 3.4V, VLED = 0.8V, CIN = 47µF, CF1 = CF2 = 0.47µF, COUT1 (VOUT to CAP) = 47µF and COUT2 (CAP to GND) = 47µF. TA= –40°C to 85°C, TJ = –40°C to 125°C. Parameter Min.
