High-precision, low-power battery level measurement solution 'MAX17055 Model Gauge m5' announced

Maxim Integrated Korea (CEO Choi Heon-jeong) announced the 'MAX17055 ModelGauge m5'. The MAX17055 ModelGauge m5 supports easier design of accurate and low-power battery level meters.

To ensure optimal performance of battery level meters, it has traditionally been necessary to extensively verify battery characteristics for each specific battery type used in a given application. This complex verification process prolongs the design phase and consumes a significant amount of resources.

Using the MAX17055's Model Gauge m5 EZ setting eliminates the need to check battery characteristics, allowing for faster time-to-market. In most cases, it maximizes operating time with a Status of Charge (SOC) error of less than 1% and operates at low power of 18/7µA to prevent excessive energy loss. It provides high convenience to users by offering accurate discharge and full charge time information.

System designers can use a battery level meter to shut down the device when the battery level is low. If the battery level meter measures battery life higher than it actually is, the device may not shut down before the voltage drops below the minimum operating point, potentially leading to unexpected failures. Conversely, if the designer shuts down the system prematurely, the system's operating time is shortened. The MAX17055 enables SOC battery level meters to provide accuracy within 1% error. This allows designers to maximize device operating time while planning system shutdowns.

The MAX17055 utilizes an industry-leading 7µA standby current in low-power operating mode. It is utilized in 1.4mm x 1.5mm WLP and is suitable for space-constrained applications. Unlike other remaining capacity measurement solutions, it has no minimum battery size limitations, making it suitable for wearables, smartwatches, smartphones, health and fitness monitors, body cameras, portable medical devices, hearables, drones, virtual reality equipment, and USB Type-C portable devices.

Bakul Damle, Director of Mobile Power Business Management at Maxim Integrated, stated, “Maxim has supplied over one billion battery level meters while continuing to innovate to help customers maximize battery usage. With the highly reliable host-side battery level meter solution MAX17055, customers can manage their batteries more efficiently.”
