Description

The MCP16501 is a cost and size optimized integrated

PMIC, compatible with Microchip’s EMPUs (Embedded

Microprocessor Units) and associated DRAM Memo-

ries. It is compatible with SAMA5DX, SAM9X6,

SAM9X7, and SAMA7G MPUs, which are supported by

dedicated device variants.

The MCP16501 integrates three DC-DC Buck

regulators and one auxiliary LDO, and provides a

comprehensive interface to the MPU.

All Buck channels can support loads up to 1A and are

100% duty cycle-capable.

The 300 mA LDO is provided such that sensitive

analog loads can be supported.

The DDR memory voltage (Buck2 output) and MPU

core voltage (Buck3 output) are selectable by means of

two three-state input pins. This method allows greater

precision in the output voltage setting by eliminating

inaccuracies due to external feedback resistors while

minimizing external component count. The voltage

selection set allows easy migration across different

generations of memory.

The default power channel sequencing is built-in

according to the requirements of the MPU. A dedicated

pin (LPM) facilitates the transition to Low-Power modes

and the implementation of Backup mode with DDR in

self-refresh (Hibernate mode).

The MCP16501 features a low no-load operational

quiescent current and it draws less than 6 µA (VIN =

4.5V, TJ = +105°C) in full shutdown.

Active discharge resistors are provided on each output.

All Buck channels support safe start-up into pre-biased

outputs.

The MCP16501 is available in a 24-pin 4 mm x 4 mm

VQFN package with an operating junction temperature

range from -40°C to +125°C. The MCP16501 also

passes automotive AEC-Q100 reliability testing.
