The LTC2904CDDB#TRPBF is a Supervisors chip belonging to the Power management and interface IC (PMIC) range. It is an ideal choice for microprocessor and microcontroller based systems since it is capable of monitoring the supply voltages at an increasing level of accuracy and also provides a highly integrated reset system.
The LTC2904CDDB#TRPBF features a wide range of features for various application requirements such as power-on-reset, manual reset, watch-dog timer reset and brownout detection, with hysteresis variation of 0.3V. It also provides an adjustable reset threshold and active high/low reset, with programmable pulse duration. The supervisor is internally formatted and expected voltage settings allows voltage monitoring in both digital and analog form and also has programmable watch-dog timer, with a range of 8ms to 8s.
In addition, the LTC2904CDDB#TRPBF has a wide operating temperature range of -40C to 85C, and accepts input voltages between +3V and +37V. It contains a low quiescent current stand-by mode, an alarm flag for voltage or temperature alarms, and a watchdog timer reset interval warning. It also has a low active reset and manual resets, plus hysteresis settings and active high/low reset.
As such, the LTC2904CDDB#TRPBF is most commonly used in microprocessor-based systems to monitor the supply voltage, preventing processor lockup. This can lead to output malfunction, stalling or error messages. Additionally, it is also used in powering down systems in high temperature applications, as well as in embedded and industrial control systems.
The LTC2904CDDB#TRPBF is an open vinyl wire wound with a three section input, output and compensation technique that within this circuitry is an MIC2930 which is an integrated voltage supervisor. The MIC2930 is responsible for detecting supply levels and supplying accurate alarm and reset signals for reset generation. This allows for tight power supply tolerances in 1.24V increments and is programmed to prevent the system from overshooting or stalling. When an input is detected at 1.24V, reset is activated.
On the other hand, other features that are available on the LTC2904CDDB#TRPBF include a watchdog timer, providing a timer interval adjust switch with a range of +8 ms to +8 sec and five reset outputs which allow for multiple reset operations according to the user’s configuration.
In conclusion, the LTC2904CDDB#TRPBF handles the more intricate aspects of power management and interface IC requirements and is an excellent choice for microprocessor and microcontroller based systems. Its broad range of features and functions, combined with its wide operating temperature range, make the LTC2904CDDB#TRPBF an ideal choice for embedded and industrial control systems.
