The LTC2919HDDB-2.5#TRMPBF is a high performance and versatile supervisor IC, which belongs to the power management IC (PMIC) - Supervisors group. Featuring two high/low voltage supply monitors, two reference voltage monitor, and two watch dog function, the LTC2919HDDB-2.5#TRMPBF has great efficiency and resilience in applications. It can be used in various fields such as automotive, computer, portable device, industry, home appliances and so on.

The LTC2919HDDB-2.5#TRMPBF allows programmable functions and provides zener-based series combinations of override and mask options which allows customizing and controllable circuit configurations that can help in extreme conditions. Its wide range supply voltage detect options can help it detect 1.25V, 1.65V, 2.5V, 3.3V and 5V input from the power sources. It also allows to setting delay times up to 25ms for debouncing and 85ms for reset pulse width by using independent and configurable resistor-adjustable internal timer. It allows to configure the reset polarity between active high and active low.

The LTC2919HDDB-2.5#TRMPBF also allow to select between pulse reset or continuous reset and power up reset. It has an in-built low power 55uA sleep mode energy and 600uA working mode current, further accelerating the energy efficiency. It has an internal stack of uncommitted CMOS spare gates and can provide open-drain type reset output rises up to 150mA current.

In view of the working principle, LTC2919HDDB-2.5#TRMPBF is typically powered by a 5V bus power. But under extreme low voltage conditions, the internal stack of uncommitted CMOS spare gates allows it to be powered by a single 1.8V power supply. It comes with a super-reg lock detection which will indicates when instantaneous dip or turn-on delay over voltage happens. Also, the real time clock support used for the delay-off timers can help the user to precisely close control the sequencing of communication and power supplies.

Unlike traditional standalone supervising ICs, an integrated dual-override for two separate power supplies can also be provided by LTC2919HDDB-2.5#TRMPBF. When RGO and RG1 is used, the chip output will be configured as an override one with minimal power-up transient responses. Thus, the override can help always keep the chip on and not to be controlled by the power supplies, offering added protection to the chip.

The dual voltage monitor of LTC2919HDDB-2.5#TRMPBF can measure both adjustable and non-adjustable high and low trip points. It offers exceptional accuracy of 0.5% or better, and provide configurable trip points with the assistance of a precision internal reference and an external divider. It also has an adjustable high and low reset accuracy option of +2% and -10%. With configurable upper and lower trip levels, and delay times options, it is well suited for monitoring wide variety of rail voltages.

In summary, LTC2919HDDB-2.5#TRMPBF is a high performance and versatile supervisor IC, featuring two high/low voltage supply monitors, two reference voltage monitor and two watch dog function, which can offer great efficiency, resilience and accuracy in applications. It has a wide range of voltage detect options and can offer adjustable trip points and delay times. Its two-override feature adds saved protection to the chip and under extreme low voltage conditions, the chip have disengaged power supplies and integrated energy saving modes.
