Microchip Technology, Inc. PMIC - Power Management - Specialized MCP16501TC-E/RMB

The MCP16501TC-E/RMB is a power management integrated circuit (PMIC) designed for use with Microchip's SAMA5DX, SAM9X6, and SAMA7G series microprocessor units (MPUs). It operates with an input voltage range of 2.7V to 5.5V and features three buck channels capable of delivering up to 1A each, along with a 300mA low dropout linear regulator (LDO). The buck channels support 100% maximum duty cycle and operate at a frequency of 2 MHz. This PMIC offers pin-selectable output voltages for the DDR and core supplies, ensuring precise voltage settings without the need for external feedback resistors. It includes built-in default channel sequencing tailored for the MPUs, facilitating low-power modes and hibernation support. The device is optimized for low quiescent current, drawing approximately 250 ¬µA in low-power mode and a maximum of 6 ¬µA in shutdown. The MCP16501 is housed in a compact 24-pin VQFN package and is rated for a junction temperature range of -40¬8C to +125¬8C. It has passed automotive AEC-Q100 reliability testing, making it suitable for high-performance applications in automotive and industrial environments.
