The DW01A is a battery protection IC, that provides protection against overcurrent, overcharge, and over-discharge and comes in a small SOT-23-6 package. It also has a very low quiescent current to prevent unnecessary battery drain.
RICOH has announced a one-cell Li-ion / polymer battery protection IC R5449 series which can drive external high-side Nch MOSFETs and provides a high-accuracy detection at overcharge and overcurrent, and a high-accuracy charge inhibition for 0V battery.
EV1527 is an OTP Encoder utilizing the CMOS technology process. EV1527 is a maximum of 20 bits providing up to 1 million codes. It can reduce any code collision and unauthorized code scanning possibilities.
