STMicroelectronics provides a recommended PCB layout in the PM8834 application note (AN5333) which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure optimal heat dissipation.
The PM8834 can be configured using the I2C interface to set the output voltage and current limits. The device has a set of registers that can be programmed to set the output voltage, current limit, and other parameters. The STMicroelectronics PM8834 datasheet and application note provide detailed information on the register settings and configuration.
The PM8834 can handle an input voltage up to 28V, but it is recommended to operate the device within the specified input voltage range of 12V to 24V for optimal performance and reliability.
The PM8834 has built-in OVP and UVP features that can be enabled through the I2C interface. The device can be configured to detect overvoltage and undervoltage conditions and respond by shutting down the output or generating an interrupt signal. The STMicroelectronics PM8834 datasheet and application note provide detailed information on implementing OVP and UVP.
The PM8834 can deliver up to 3A of output current, but the actual output current capability depends on the input voltage, output voltage, and thermal conditions. The device has a built-in overcurrent protection (OCP) feature that limits the output current to prevent damage to the device.
