Long battery life achieved through low standby current, true shutdown, and high efficiency
Optimized for wearable, consumer, and IoT products through minimized heat dissipation and current.

Maxim Integrated Korea announced the nanopower boost regulator 'MAX17222'.

The MAX17222 enables the longest battery life in an ultra-small form factor for wearable, consumer, and Internet of Things (IoT) product designs with a minimum standby current ( _IQ ) of only 300nA.

The MAX17222 provides an input voltage of 0.4–5.5 V, an input current limit of 500 mA, and an output voltage of 1.8–5 V. It is compatible with low-voltage batteries and supercapacitors.

The MAX17222 is suitable for wearable devices because it minimizes standby current, heat dissipation, and shutdown current. With a current draw of 0.5nA in True Shutdown mode, it prevents battery depletion, maximizing battery life, and eliminates the need for an external shut-off switch.

With internal compensation circuitry, the MAX17222 implements a power solution using only a single register and a small output filter. For ease of use, it is available in 0.88mm x 1.4mm 6-bump WLP and 2mm x 2mm 6-pin standard uDFN packages. The operating temperature range is -40°C to +85°C.

Meng He, Senior Business Manager at Maxim Integrated, said, “The MAX17222 combines low standby current, true shutdown, and high efficiency to provide long battery life, enabling customers to produce optimal smart connected products.”
