1.2A/40V Fully Integrated Linear Charger for 1 Cell Li-ion Battery

ETA4257 is a single cell, fully integrated constant current (CC)/constant voltage (CV) Li-ion battery charger. Its compact package with minimum external components requirement makes the ETA4257 ideal for portable applications. No external sense resistor or blocking diode is necessary for the ETA4257 • 40V input standoff voltage\n\n• 4.2V charge termination voltage\n\n• 2.6V trickle charge threshold\n\n• Charge current programmable, up to 1.2A\n\n• 400nA BAT current when no charging\n\n• Soft-start limits in-rush current\n\n• Fault and Charge Status Indicator\n\n• DFN3x3-10;

SOT23, Single-Supply, Low-Noise, Low-Distortion, Rail-to-Rail Op Amps

General Description The MAX4249–MAX4257 low-noise, low-distortion operational amplifiers offer Rail-to-ail®outputs and single supply operation down to 2.4V. They draw only 400µA of quiescent supply current per amplifier while featuring ultra-low distortion (0.0002 THD), as well as low input vol
