Frequently Asked Questions
What does the TLV840MADL52DBVR do?
The TLV840MADL52DBVR is a single-channel low-voltage supervisor and reset IC that monitors a supply voltage rail and asserts a reset signal when the voltage falls below an adjustable threshold. It also provides a programmable reset time delay, ensuring the system stays in reset long enough for power rails to stabilize before releasing the processor or microcontroller.
Is the reset threshold adjustable on the TLV840MADL52DBVR?
Yes, the TLV840MADL52DBVR features an adjustable reset threshold, allowing designers to set the precise voltage level at which the reset output is asserted. This flexibility enables the device to supervise a wide variety of supply rails beyond standard 3.3V or 5V levels, making it suitable for custom or non-standard power supply monitoring needs.
What reset delay options does the TLV840MADL52DBVR provide?
The TLV840MADL52DBVR includes a programmable reset time delay feature, which allows the reset assertion period to be set by an external component. This programmable delay ensures the microcontroller or processor remains in reset for a sufficient time after power-up, preventing premature initialization before supply rails have fully settled to their nominal values.
What package does the TLV840MADL52DBVR come in?
The TLV840MADL52DBVR is housed in a 5-pin SOT-23 surface-mount package (JESD-30 code R-PDSO-G5). This miniature package is one of the smallest available for supervisor ICs, making it ideal for space-constrained portable electronics, IoT sensor nodes, and wearable device PCB designs.
What are typical applications for the TLV840MADL52DBVR?
Typical applications include microcontroller reset supervision in embedded systems, brownout detection in battery-powered IoT and wearable devices, power supply monitoring in industrial PLCs, and system reset management in consumer electronics. The adjustable threshold extends its use to 1.8V, 2.5V, and other non-standard low-voltage supply rails common in modern embedded designs.
