Key Features
- Fixed 3.0 V reset threshold with active-low push-pull output providing guaranteed microcontroller reset assertion during power brownout without external components
- Low quiescent current consumption in a 3-pin SOT-23 package supporting -40°C to +125°C operation for battery-powered and industrial reset monitoring
- Manual reset input (MNL RST) support enabling hardware-triggered system resets from a pushbutton or host GPIO in embedded microcontroller designs
Applications
The TLV809EF30DBZR is designed to provide reliable power-on and brownout reset signals for microcontrollers and FPGAs in industrial, consumer, and communications equipment. It monitors the supply rail and asserts the active-low RESET pin whenever voltage drops below the fixed 3.0 V threshold, ensuring orderly system restart and preventing undefined microcontroller behavior during power transients. Its 3-pin SOT-23 form factor and -40°C to +125°C range make it suitable for automotive accessory boards, industrial sensor nodes, and handheld instruments.

Frequently Asked Questions
At what supply voltage does the TLV809EF30DBZR assert its reset output, and how precise is the threshold?
The TLV809EF30DBZR asserts its active-low RESET output when the monitored supply falls below the fixed 3.0 V threshold, with typical threshold accuracy of ±2%, meaning the actual trip point lies between 2.94 V and 3.06 V, which is tight enough to protect 3.3 V microcontrollers whose minimum operating voltage is around 2.7 V.
How does the active-low push-pull output of the TLV809EF30DBZR simplify microcontroller reset circuit design?
Because the TLV809EF30DBZR uses a push-pull output rather than an open-drain output, it does not require an external pull-up resistor to drive the microcontroller reset line high when supply is valid, reducing the BOM by 1 component and eliminating the RC time-constant error that external resistors can introduce in reset timing circuits.
Over what temperature range does the TLV809EF30DBZR operate, and which environments does that cover?
The TLV809EF30DBZR is rated for -40°C to +125°C junction temperature, spanning automotive under-hood conditions, industrial outdoor enclosures, and commercial indoor electronics, making it a single qualified part for designs that need a common reset supervisor across multiple product tiers without separate automotive and commercial SKUs.
How compact is the TLV809EF30DBZR, and what PCB area does it require?
The 3-pin SOT-23 package measures approximately 1.3 mm × 2.9 mm with 0.95 mm pitch, occupying roughly 4 mm² of PCB footprint, which is significantly smaller than an 8-pin SO package reset supervisor, allowing the TLV809EF30DBZR to fit on densely populated boards such as wearable modules and miniature IoT sensor nodes.
Does the TLV809EF30DBZR support a manual reset input, and how would that be used in a system?
Yes, the TLV809EF30DBZR includes a manual reset (MNL RST) input that allows an external pushbutton or a host microcontroller GPIO to assert the reset line independently of supply voltage, enabling factory test routines, firmware recovery sequences, and end-user resets without cycling power, adding functional flexibility with no additional ICs.
