DA9080

AI生成コンテンツ: The document details the default register settings and configurations for the DA9080-63FCBx variant, including voltage levels for four channels and LDO, channel assignments, ADC status, and I2C communication parameters. It provides a comprehensive register map with default values, phase interleaving settings, power good assignments, and discharge enablement. The variant table lists package sizes and shipment forms. Revision history and status definitions clarify document updates and approval status. RoHS compliance is confirmed with supplier certifications.

AI生成コンテンツ: Power supply circuits for RZ/N2L, RZ/T2L, and RZ/T2M require a specific power-up sequence: 1.1 V and 1.8 V supplies must be activated before the 3.3 V supply, all within 100 ms. Power-down reverses this order. The DA9080 PMIC manages these voltages with multiple channels and supports system integration via I2C control. Detailed power trees illustrate connections for different MPU variants, emphasizing stable clock input and monotonic voltage rise. Bulk capacitors and pre-regulator connections improve stability. Power on/off sequences and variant ordering information are also provided.

AI生成コンテンツ: Power supply circuits for RZ/T2H and RZ/N2H systems use DA9080, DA9220, and DA9217 devices to meet specific power on/off sequences and voltage requirements. The DA9080 configures five channels for efficient power management, while DA9220 and DA9217 provide buck converter outputs with adjustable voltages up to 3.3 V. Power-up starts at 0.8 V and progresses through 1.8 V, 1.1 V, and 3.3 V within 100 ms, maintaining reset low. Power-down reverses this order. The document details timing, register settings, and power tree diagrams to guide system design and ensure stable operation with peripherals such as PCIe and memory components.

AI生成コンテンツ: Unused pins of the DA9080 power management IC require specific configurations to prevent noise, increased current consumption, or device damage. Power pins not in use should be connected to ground or left floating as specified. I2C interface pins need pull-up resistors or can be grounded if unused. Buck converter-related pins must be grounded or left floating depending on function. Proper adherence to these guidelines ensures stable operation and avoids malfunction.
