TPS3836E18DBVT Texas Instruments Integrated Circuit (SOT23 (5-Pin)) In Stock
The TPS3836E18DBVT is a single-channel voltage supervisor and reset IC with a fixed 1.8 V threshold. It monitors power supply rails and asserts an active-low reset signal during undervoltage conditions, with a factory-set timeout delay to ensure orderly microcontroller startup. Housed in a 5-pin SOT-23 package, it suits portable electronics, IoT nodes, and low-voltage embedded systems requiring reliable power-on reset.

- Low quiescent current suitable for battery-powered designs
What is TPS3836E18DBVT used for?
The TPS3836E18DBVT is used in microcontroller and microprocessor-based systems to assert a clean power-on reset, preventing false code execution during power-supply ramp-up or brownout events. It is particularly suited to 1.8 V IoT sensor nodes, wearable devices, and handheld instruments where board space is limited and the SOT-23 footprint minimises PCB area consumption. Embedded systems requiring a reliable watchdog-independent hardware reset path for FPGAs, DSPs, or Flash memory also benefit from its fixed threshold accuracy.

Frequently Asked Questions
At what supply voltage does TPS3836E18DBVT assert its reset output?
The TPS3836E18DBVT asserts its active-low reset output when the monitored supply voltage drops below the fixed 1.8 V threshold. The reset remains asserted until the supply rises above this threshold and a factory-set timeout delay of typically 200 ms elapses, ensuring the processor starts into a stable power environment.
How does TPS3836E18DBVT simplify a 1.8 V microcontroller reset circuit compared to a discrete resistor-divider solution?
The device integrates the threshold comparator, reference voltage, and timeout timer in a single 5-pin SOT-23 package, eliminating the 2-resistor divider, external comparator, and RC delay network that a discrete solution needs. This reduces BOM count by at least 4 components and saves approximately 10 mm² of board area.
Can TPS3836E18DBVT monitor a 3.3 V rail directly?
No. The TPS3836E18DBVT has a fixed 1.8 V reset threshold and is designed specifically for 1.8 V rail supervision. For 3.3 V rail monitoring in the same TPS3836 family, an alternative part with a 3.3 V threshold should be selected; using TPS3836E18DBVT on a 3.3 V rail would keep the reset permanently deasserted since 3.3 V always exceeds the 1.8 V threshold.
Which embedded application domains benefit most from TPS3836E18DBVT?
IoT sensor nodes, wearable electronics, and portable medical monitors running at 1.8 V benefit most because the SOT-23-5 package occupies under 9 mm² of PCB area and the single-supply operation suits coin-cell or LDO-regulated 1.8 V power trees. Industrial edge gateways with low-voltage FPGAs also use it for guaranteed power-on sequencing.
Does TPS3836E18DBVT require any external capacitors or resistors for operation?
The device requires no external resistors for threshold setting because the 1.8 V trip point is factory-trimmed internally. A small 100 nF decoupling capacitor on the supply pin is recommended by the datasheet for noise immunity, but no timing capacitor or feedback resistors are needed, keeping the total external component count to 1 passive part.
