M61041FP
4-Battery Version, No Reset Pin
REJ03F0063-0100Z
Rev.1.0
Sep.19.2003
This product is currently under development, and its specifications, pin assignments, etc., are subject to change.
Description
The M61041FP is an semiconductor IC device developed for smart battery packs. It incorporates all the analog
circuitry required by smart batteries in a single chip. When used in conjunction with a microprocessor, it allows the
implementation of a variety of functions, such as battery capacity detection, through the addition of minimal
peripheral devices and is ideal for smart battery system (SBS) battery packs.
The M61041FP also has an on-chip overcurrent detect circuit so that the FET for controlling battery charging and
discharging is protected regardless of the processing speed of the microprocessor.
The microprocessor can change the amplifier gain of the charge/discharge current detect circuit, so battery capacity
detection accuracy is increased. In addition, the M61041FP incorporates a linear regulator that allows it to function
as the power supply for the microprocessor, thereby simplifying power supply block design.
Features
• On-chip high-gain op-amp for monitoring charge and discharge current.
• On-chip overcurrent detect circuit to protect FET.
• Charge/discharge FET can be controlled from microprocessor.
• Power-save function for reducing current consumption.
• 5.2 V operation to reduce microprocessor current consumption.
• High-voltage device (absolute maximum rating: 33 V).
Application
• Smart battery system (SBS) battery packs
