Product Details
AD8452ASTZ - Precision Battery Formation and Test AFE/PWM Controller
AD8452ASTZ from Analog Devices Inc. is a precision integrated analog front end, control-loop processor and PWM modulator for battery formation and test systems in a 48-lead LQFP.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
AD8452 integrates current and voltage measurement, error amplifiers, automatic constant-current/constant-voltage switchover and a programmable PWM modulator for bidirectional battery formation and test equipment.
Key Advantages
Combines precision sensing, CC/CV loop control and PWM generation in one device.
Provides low offset drift, high common-mode rejection and automatic loop switchover for accurate battery cycling.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
