A Moortec PVT (Process, Voltage, Temperature) monitoring logic design can
|
||||
include many different units.
|
||||
Such a design will usually consists of several Moortec's embedded analog IPs,
|
||||
and a single Moortec controller (mr75203) to configure and control the IPs.
|
||||
|
||||
Some of the Moortec's analog hard IPs that can be used in a design:
|
||||
*) Temperature Sensor (TS) - used to monitor core temperature (e.g. mr74137).
|
||||
*) Voltage Monitor (VM) - used to monitor voltage levels (e.g. mr74138).
|
||||
*) Process Detector (PD) - used to assess silicon speed (e.g. mr74139).
|
||||
*) Delay Chain - ring oscillator connected to the PD, used to measure IO
|
||||
based transistors (e.g. mr76008 ring oscillator at 1.1V, mr76007 ring
|
||||
oscillator at 1.8V).
|
||||
*) Pre Scaler - provides divide-by-X scaling of input voltage, which can then
|
||||
be presented for VM for measurement within its range (e.g. mr76006 -
|
||||
divide by 2 pre-scaler).
|
||||
|
||||
TS, VM & PD also include a digital interface, which consists of configuration
|
||||
inputs and measurement outputs.
|
||||
|
||||
Some of the units have number of series, each series can have slightly
|
||||
different characteristics.
|
||||
|
||||
The mr75203 binding describes configuration for the controller unit, but also
|
||||
for some of the analog IPs.

Description
|
||||
-----------
|
||||
|
||||
The MAX31760 integrates temperature sensing along with precision PWM fan
|
||||
control. It accurately measures its local die temperature and the remote
|
||||
temperature of a discrete diode-connected transistor, such as a 2N3906,
|
||||
or a thermal diode commonly found on CPUs, graphics processor units (GPUs),
|
||||
and other ASICs. Multiple temperature thresholds, such as local
|
||||
high/overtemperature (OT) and remote high/overtemperature, can be set by an
|
||||
I2C-compatible interface. Fan speed is controlled based on the temperature
|
||||
reading as an index to a 48-byte lookup table (LUT) containing
|
||||
user-programmed PWM values. The flexible LUT-based architecture enables
|
||||
the user to program a smooth nonlinear fan speed vs. temperature transfer
|
||||
function to minimize acoustic fan noise. Two tachometer inputs allow
|
||||
measuring the speeds of two fans independently. When the local or remote
|
||||
OT threshold is exceeded, the SHDN pin is asserted low and can be used to
|
||||
shut down the system. A dedicated ALERT pin reports that either a local or
|
||||
remote high-temperature threshold has been exceeded.
|
||||
|
||||
Temperature measurement range: from -55°C to 125°C
|
||||
|
||||
Temperature Resolution: 11 Bits, ±0.125°C

The TPS546D24A is a highly integrated, non-isolated DC/DC converter capable
|
||||
of high frequency operation and 40-A current output from a 7-mm x 5-mm
|
||||
package.
|
||||
|
||||
Two, three, and four TPS546D24A devices can be interconnected
|
||||
to provide up to 160 A on a single output. The device has an option to
|
||||
overdrive the internal 5-V LDO with an external 5-V supply via the VDD5
|
||||
pin to improve efficiency and reduce power dissipation of the converter.
