Frequently Asked Questions
What reset threshold voltage does TCM809RVNB713 monitor, and can the threshold be adjusted externally?
TCM809RVNB713 monitors a fixed reset threshold in the 2.55 V to 2.7 V range; the threshold is not adjustable externally. This makes it ideal for supervising 2.6 V or 2.5 V regulated rails without any external resistor divider, reducing component count and BOM complexity.
What type of reset output does TCM809RVNB713 provide, and how long is the reset pulse guaranteed?
The device provides an active-low push-pull RESET output, which directly drives most microcontroller reset pins without a pull-up resistor. The guaranteed minimum reset pulse width is 140 ms, which is long enough to satisfy the power-on reset timing requirements of the majority of 8-bit and 32-bit microcontrollers operating at typical clock frequencies.
How does the 3-pin SOT-23 package of TCM809RVNB713 benefit PCB layout in a compact IoT module?
The SOT-23-3 package measures approximately 2.9 mm × 1.6 mm, occupying under 5 mm² of board area. This is among the smallest footprints available for a voltage supervisor, allowing designers to place the device immediately adjacent to the microcontroller VCC pin and minimize trace length for fast brownout detection response.
Is TCM809RVNB713 a good substitute for pin-compatible voltage supervisors such as MCP809 or AP809 series?
TCM809RVNB713 is part of the Microchip SOT-23-3 supervisor family and is functionally equivalent to many AP809, MAX809, and MCP809 variants with matching 2.63 V threshold grades. Designers can substitute between these parts provided the threshold tolerance, reset delay of at least 140 ms, and push-pull output polarity match the target design requirements.
