The MAX17823AGCB/V+ is a multi-function fuel-gauging controller designed for battery management in portable, power-constrained applications. Using an integrated memory to store the composed algorithm, it continuously reads battery voltage, current and temperature data from a series of external sensors to accurately track remaining capacity. The controller comes with a feature set and performance characteristics that aim to provide high accuracy, ease of integration, low power consumption and fast time-to-market.

The impressive list of integrated features also reduces the need for external components, allowing for a design that is both faster and more cost-effective. This makes the MAX17823AGCB/V+ an ideal choice for battery management applications such as mobile phones, digital cameras, Notebooks, e-books, game console and toys, as well as smart watches.

The MAX17823AGCB/V+ employs a 12-bit A/D converter and Delta-Sigma (ΔΣ) modulator to support 1 µA of load current accuracy and load-change rejection up to 128 Hz with a 0.25Ω MOSFET pre-programmed with user-selected parameters for fast and easy design even for the most challenging applications. Furthermore, the fuel-gauging controller supports multiple compensation points, allowing for varying conditions such as discharge rate, battery temperature and device temperature.

The MAX17823AGCB/V+ implements a wide range of functions to fuel-gauge the batteries inside mobile devices, including:

• 12-bit A/D converter to read PrC, SoC and total available capacity
• Delta-Sigma (ΔΣ) modulator to measure load current
• Pre-programmed parameters to help configure the charge algorithm easily
• High accuracy, up to 1 µA
• 1.5 μA I_SB in sleep mode and 7 mA in active mode
• NTC resistor temperature measurement
• Buffer for multiple compensations points
• Active watchdog for data safety
• Automatic energy offsets for load current corrections
• Smart sleep mode to optimize power consumption and performance

The MAX17823AGCB/V+ monitor the state of the battery, such as PrC, SoC and total available capacity, through a 12-bit A/D converter and Delta-Sigma (ΔΣ) modulator. Delta-Sigma Modulators allow for highly accurate load current measurement, with a 0.25Ω MOSFET providing load current range up to 16mA. The Fuel-Gauging Controller supports multiple compensations points, allowing for varying conditions such as discharge rate, battery temperature and device temperature. Furthermore, the device also comes with a buffer for NTC resistor temperature measurement, energy offsets for load current compensation and an active watchdog for data safety.

In addition to the fuel gauging functions, the MAX17823AGCB/V+ also contains a full charging system with implemented overvoltage, overcurrent and overtemperature protection. The device supports charge currrent levels up to 1.5A and shutdown current at 10 µA. It also features a sync-type charge cycle completer, allowing a dead battery to recover without the need for an external cycle completer.

The MAX17823AGCB/V+ also comes equipped with a smart sleep mode to optimize performance and power consumption. This mode allows the device to enter low-power sleep mode while maintaining accuracy. Furthermore, it features an automatic transition to sleep mode and wakeup signals, allowing for a seamless transition to sleep without user intervention.

Overall, the MAX17823AGCB/V+ offers industry-leading accuracy, ease of integration and extensive feature set for effectively managing batteries in space-limited and power-constrained applications. This makes the device an ideal choice for digital cameras, smart watches and other similar personal electronics.
