2 / 8 page SOT23, Single-Cell Li+ Battery Charger for Current-Limited Supply 2 _______________________________________________________________________________________ ABSOLUTE MAXIMUM RATINGS Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. IN, GATE to GND....................................................-0.3V to +26V BATT, EN, CT to GND ..............................................-0.3V to +6V GATE to IN................................................................-6V to +0.3V GATE Continuous Current.................................-10mA to +10mA Continuous Power Dissipation (TA = +70 °C) (Note 1) 6-Pin SOT23 (derate 8.1mW/ °C above +70°C).............0.65W Operating Temperature Range ...........................-40°C to +85 °C Storage Temperature Range ..............................-65°C to +150 °C Maximum Junction Temperature ......................................+150 °C Lead Temperature (soldering, 10s) (Note 2) ...................+300 °C ELECTRICAL CHARACTERISTICS (VIN = 10V, VBATT = 4.2V for MAX1736EUT42 or 4.1V for MAX1736EUT41, TA = 0 °C to +85°C. Typical values are at TA = +25°C, unless otherwise noted.)

Note 2: This device is constructed using a unique set of packaging techniques that impose a limit on the termal profile the device can be exposed to during solder attach and rework. This limit permits only the use of the solder profiles recommended in the industry stan- dard specification, IPC/JEDEC J-STD-020A, paragraph 7.6, Table 3 for the IR/VPR and Convention reflow. Pre-heating is required. Hand or wave soldering is not allowed. |
