Power Management
The LTC
®
2928 is a four channel cascadable power
supply sequencer and high accuracy supervisor. Sequenc-
ing thresholds, order and timing are configured with just a
few external components, negating the need for PC board
layout or software changes during system development.
Multiple LTC2928s may be easily connected to sequence
an unlimited number of power supplies.
Sequence outputs control supply enable pins or
N-channel pass gates. Precision input comparators with
individual outputs monitor power supply voltages to 1.5%
accuracy. Supervisory functions include undervoltage
and overvoltage monitoring and reporting as well as
µP
reset generation.
RST
may be forced high to complement
margin testing.
Application faults, whether internally or externally gener-
ated, can shutdown all controlled supplies. The type and
source of faults are reported for diagnosis. Individual
channel controls are available to independently exercise
enable outputs and supervisory functions.
A high voltage input allows the LTC2928 to be powered
from voltages as high as 16.5V. A buffered reference
output permits single negative power supply sequencing
and monitoring operations.

cubemx sets TF to 4bit, but the file shows 1bit mode
Cube MX 5.30 is the latest version. When reading and writing TF cards via SDIO, the mode is set to 4-bit. However, the generated c file is always in 1-bit mode. It's strange. Could it be that the 4-bi...
