Key Features
- Programmable reset time delay allows designers to tune reset assertion duration from milliseconds to seconds without external RC networks
- Adjustable threshold detection covers a wide range of supply voltages for flexible multi-rail system monitoring
- Manual reset input (MR pin) enables direct hardware reset control from a pushbutton or external logic signal
- Ultra-compact 5-pin SOT-23 package suits space-constrained processor boards and portable instrument designs
Applications
TLV840MADL08DBVR is used in microcontroller-based systems, embedded processors, and FPGA boards that require reliable power-on reset and brownout recovery with a precisely controlled reset hold time. The adjustable reset delay is particularly valuable in systems with slow-rising power supplies or storage capacitors where a fixed-timeout supervisor would release reset too early. It is also deployed in industrial PLCs and handheld instrumentation where the manual reset pin enables front-panel or test-jig initiated hardware resets.

Frequently Asked Questions
How does the adjustable reset time delay in TLV840MADL08DBVR benefit systems with slowly rising supply voltages?
TLV840MADL08DBVR allows the reset assertion time to be set by an external capacitor connected to the delay pin, giving designers control over the reset pulse width from a few milliseconds to several seconds. In systems where the power supply rises slowly due to large bulk capacitance or high inrush limiting, a programmable delay ensures the processor core voltage is fully stable before the reset signal is released. This prevents false starts that occur with fixed-timeout supervisors rated for faster supply ramp rates.
What is the package and channel count of TLV840MADL08DBVR, and how does it fit on a compact processor module?
TLV840MADL08DBVR is a single-channel voltage supervisor in a 5-pin SOT-23 package, which occupies approximately 3 mm x 1.75 mm board area including courtyard. The 5 pins cover VCC, GND, reset output, manual reset input, and the delay capacitor pin, providing a complete supervisor function with minimal PCB real estate. This is well-suited for tight layouts around 32-bit MCUs and application processors where multiple supply monitors share limited board space.
When is TLV840MADL08DBVR a better choice than a fixed-threshold supervisor for a multi-voltage embedded design?
TLV840MADL08DBVR features an adjustable threshold, allowing it to monitor supply voltages other than standard 1.8 V, 2.5 V, 3.3 V, or 5 V rails by setting an external resistor divider. A fixed-threshold device would require multiple SKUs to cover different supply levels in the same product family, whereas a single TLV840MADL08DBVR can be configured for any target threshold in the supported range. The 5-pin SOT-23 footprint and programmable delay pin further reduce per-design BOM variation across product variants.
