Maxim Integrated MAX713CSE: NiCd/NiMH Battery Fast-Charge Controller
The MAX713CSE from Maxim Integrated is a sophisticated charge-management IC designed for fast and efficient charging of nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) batteries. This charge controller is housed in a 16-pin narrow SO package, making it a compact solution for portable electronic devices where space is at a premium.
One of the key features of the MAX713CSE is its ability to charge batteries rapidly without compromising their life or performance. It achieves this through an advanced algorithm that monitors the voltage and temperature of the battery to provide the optimal charge rate. This results in shorter charge times and extends the overall lifespan of the battery.
The MAX713CSE incorporates a range of safety features to ensure the charging process is secure and reliable. It includes a prequalification stage that checks the battery condition before initiating the fast-charge cycle. If the battery is overly discharged or has a temperature outside of the safe range, the MAX713CSE will postpone fast charging until the battery conditions are within acceptable limits.
Another notable feature of this charge controller is its flexibility. It supports batteries with different cell counts, and its fast-charge current is programmable via an external resistor. This makes the MAX713CSE a versatile component suitable for a wide range of applications, from handheld devices to backup power systems.
The MAX713CSE also offers a transition to trickle charge upon completion of the fast charge, ensuring that the battery remains fully charged without overcharging. This transition is automatic and based on the detection of a voltage peak or when the charge time has elapsed, which adds to the safety and maintenance of the battery.
In summary, the Maxim Integrated MAX713CSE is an efficient, safe, and flexible charging solution for NiCd and NiMH batteries. Its compact design, coupled with its advanced charging algorithm and programmable features, make it an ideal choice for a variety of portable electronic applications where reliable battery management is essential.
