The M3406 is a constant frequency, current mode step-down converter. The device integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. It is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. The output voltage can be regulated as low as 0.6V. The M3406 can also run at 100% duty cycle for low dropout operation, extending battery life in portable system. This device offers two operation modes, PWM control and PFM Mode switching control, which allows a high efficiency over the wider range of the load. The M3406 is offered in a low profile 5-pin, SOT package, and is available in an adjustable version.

CW1353 series, a lithium battery protection chip with built-in high-precision detection and delay circuits, suitable for 45-cell lithium-ion or lithium polymer battery packs. It provides overcharge detection, over-discharge detection, overcurrent detection, equalization, open-circuit detection, and high/low temperature protection during charging and discharging. The CW1353 has a built-in MOSFET driver function, supporting external PWM signals to control the DO terminal output via the DCTRL terminal, enabling motor speed control and soft-start functions. |CW1353AFCP|CW1353AFCP DATASHEET|CW1353AFCP RESELLER IN INDIA|CW1353AFCP RESELLER IN MUMBAI|CW1353AFCP RESELLER NEAR ME|CELL WISE DISTRIBUTOR IN INDIA|CELL WISE DISTRIBUTOR IN MUMBAI|CELL WISE DISTRIBUTOR NEAR ME|

The CL4056D is a standalone linear Li-ion battery charger with ESOP8 package. With few external components, CL4056D is well suited for a wide range of portable applications. Charging current can be programmed by an external resistor. In standby mode, supply current will be reduced to around 35uA. When the input voltage is disconnected, CL4056D enters the sleep state, and the battery leakage current will drop below 1uA. Other features include UVLO, automatic recharge, charge status indicators and thermal regulation.
