    Precision Integrated Analog Front End, Controller,
    and PWM for Battery Test and Formation Systems AD8452 Data Sheet
    FEATURES GENERAL DESCRIPTION CC and CV battery test and formation modes with
    transparent and automatic switchover, for systems of
    20 Ah or less
    Precise measurement of voltage and current
    Independent feedback control blocks
    Highly accurate, factory trimmed instrumentation and
    differential amplifiers
    In-amp for current sense gain: 66 V/V
    Difference amplifier for voltage sense gain: 0.4 V/V
    Stable over temperature: offset voltage drift <0.6 ОјV/В°C
    (maximum)
    Gain drift: <3 ppm/В°C (maximum)
    Current sense CMRR: 120 dB minimum
    Popular SMPS control for charge/discharge
    High PWM linearity with internal ramp voltage
    50 kHz to 300 kHz user controlled switching frequency
    Synchronization output or input with adjustable phase shift
    Programmable soft start The AD8452 combines a precision analog front-end controller
    and switch mode power supply (SMPS), pulse-width modulator
    (PWM) driver into a single silicon platform for high volume
    battery testing and formation manufacturing. A precision ...
