Introducing the Holtek Battery Monitoring ICs HT32F616xx
As the world becomes increasingly reliant on battery-powered devices, the importance of battery monitoring cannot be overstated. From cordless screwdrivers to vacuum cleaners, batteries have become an indispensable part of our daily lives. However, if not monitored properly, batteries can be damaged, shorten their service life, or even explode.
This is where Holtek's new Cortex-M0+ HT32F616xx Battery Monitoring MCUs come in. These MCUs offer integrated voltage monitoring and passive cell balancing for 3-8 lithium-ion cells, making them an ideal solution for a wide range of battery-powered devices.
The HT32F616xx MCUs are based on the Arm Cortex-M0+ processor core, which is tightly coupled with the Nested Vectored Interrupt Controller (NVIC), SysTick timer, and advanced debug support. This allows the MCUs to operate at a frequency of up to 16 MHz, providing maximum efficiency.
In addition to the Cortex-M0+ processor core, the HT32F616xx MCUs also provide up to 32 KB of embedded Flash memory for code/data storage and 2 KB of embedded SRAM memory for system operation and application program usage. This makes them a powerful and flexible solution for a wide range of battery-powered devices.
One of the key features of the HT32F616xx MCUs is their accumulative cell voltage monitor. This monitor is used to monitor an accumulative voltage from 1 to N and output the divide-by-N voltage. This allows the MCUs to accurately monitor the voltage of each cell in a battery pack, ensuring that the battery is not operated beyond its voltage and current limits and does not overheat.
In addition to the accumulative cell voltage monitor, the HT32F616xx MCUs also include a high-accuracy voltage regulator, two discharge N-type MOSFET gate-drivers, and a charge N-type MOSFET gate-driver. These features are provided for 3 to 8 cell Li-ion rechargeable battery applications, making the HT32F616xx MCUs an ideal solution for a wide range of battery-powered devices.
Another key feature of the HT32F616xx MCUs is their power-saving modes. These modes provide the flexibility for maximum optimization between wakeup latency and power consumption, making them an ideal solution for low-power applications.
Overall, the HT32F616xx Battery Monitoring MCUs from Holtek are a powerful and flexible solution for a wide range of battery-powered devices. With their integrated voltage monitoring and passive cell balancing, these MCUs ensure that batteries are monitored properly, preventing damage and extending their service life. If you're looking for a reliable and efficient solution for your battery-powered device, the HT32F616xx MCUs are definitely worth considering.
