Audio-Technica WIRE HANGER FOR C,H,O & SC ELE

The AT8451 (AD8451 family) is a high‑accuracy analog front‑end controller used in battery charging and discharging equipment. It monitors battery current and voltage through precision amplifiers and controls external power converters to maintain constant current (CC) and constant voltage (CV) operation.

The device integrates instrumentation amplifiers, voltage sensing circuits, and control loops that enable precise measurement and regulation of battery charging parameters. It is widely used in lithium‑ion battery formation systems, battery test equipment, and programmable power supplies.
