How Does The HW Monitor Click Board™ Work?
The HW Monitor Click Board™ is based on the LM96080, a system hardware monitor from Texas Instruments that performs power supply, temperature, and fan monitoring for various embedded systems. The LM96080 provides seven analogue inputs spread across the terminals on the top of the board labelled from IN0 to IN6, a temperature sensor, a delta-sigma ADC, two fan speed counters, watchdog registers, and a variety of inputs and outputs on a single chip. It continuously converts analogue inputs to 10-bit resolution with a 2.5mV LSB, yielding input ranges of 0 to 2.56V. The analogue inputs are intended to connect to several power supplies in a typical communications infrastructure system.
This Click board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings with a maximum frequency of 400kHz. The LM96080 includes an analog filter on the I2C lines that improves noise immunity and supports the timeout reset function on SDA and SCL pins, preventing I2C bus lockup. Also, the LM96080 allows choosing the least significant bits (LSB) of its I2C slave address using the SMD jumpers labelled ADDR SEL.
The LM96080 is especially suited to interface with linear and digital temperature sensors such as LM73, LM75, LM56, LM57, LM26, LM27, LM26LV, or other LM96080 via the BTI pin on one of the unpopulated headers. Temperature can be converted to a 9-bit or 12-bit two's complement word with resolutions of 0.5°C or 0.0625°C LSB, respectively. On the same header, in addition to the BTI pin, there is also a GPI pin, which, in addition to its function as a general-purpose input pin, can also serve as a chassis intrusion detection input. The chassis intrusion input is designed to accept an active high signal from an external circuit that latches, such as when the cover is removed from the computer.
Next in this board's series of additional features are the fan inputs, labelled FAN1 and FAN2, that can be programmed to accept either fan failure indicator programmed to be active high or active low or tachometer signals. Fan inputs measure the period of tachometer pulses from the fans, providing a higher count for lower fan speeds. The full-scale fan counts are 255 (8-bit counter), representing a stopped or slow fan. Based on a count of 153, nominal speeds are programmable from 1100 to 8800 RPM. Signal conditioning circuitry is also included to accommodate the slow rise and fall times.
The last header contains functions such as an external interrupt input INT IN, a master reset for external purposes RST OUT, and a single power switch pin GPO. The INT IN active low interrupt provides a way to chain the interrupts from other devices through the LM96080 to the host, the RST_OUT is intended to provide a master reset to devices connected to this line, while the GPO pin is an active low NMOS open drain output intended to drive an external power PMOS for software power control or can be utilized to control power to a cooling fan. The LM96080 also possesses a general reset signal routed on the RST pin of the mikroBUS™ socket to reset the LM96080, and an additional interrupt signal, routed on the INT pin of the mikroBUS™ socket whenever some of the external interrupts like INT_OUT, interrupt from the temperature sensor, or when a chassis detection event occurs.
The HW Monitor Click Board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
