Product details

Reset supervisor for automotive and industrial rails

The Texas Instruments TPS3836L30QDBVRQ1 is a single-channel voltage supervisor designed to monitor a 2.64V threshold rail and assert a reset signal to the processor when the supply drops below that level. The active-low, push-pull output drives the reset line directly without needing an external pull-up resistor, simplifying the BOM for ECU, ADAS, and motor-control modules.

2.64V threshold — matching the rail to the supervisor

The 2.64V threshold is set for monitoring a 3.3V nominal supply rail. When the rail decays below that level, the supervisor asserts reset with a minimum timeout of 10ms, giving the supply time to recover before the processor is released from reset. This is a standard fit for 3.3V MCU and DSP systems where brownout protection is required.

SOT-23-5 package — layout and footprint

Housed in a SOT-23-5 (SC-74A) package, the TPS3836L30QDBVRQ1 is a surface-mount device with a compact footprint suited for space-constrained automotive PCBs.

For production programs requiring long-term supply assurance, this part presents no imminent LTB risk. ROHS3 compliant.

Frequently asked questions

Is TPS3836L30QDBVRQ1 automotive qualified and AEC-Q100 compliant?

Yes, the TPS3836L30QDBVRQ1 is part of the Automotive, AEC-Q100 series, making it qualified for automotive-grade applications including under-hood and chassis domains.

Can TPS3836L30QDBVRQ1 be used in a -40°C environment?

Yes, the operating temperature range is -40°C to 125°C, covering cold-crank and high-temperature under-hood conditions.

What is the closest functional second-source to TPS3836L30QDBVRQ1?

The TLV803ED29DBZR is a functional peer with an active-low reset and a 33ms minimum reset timeout, but its output is open-drain (requires a pull-up resistor) and its threshold is 2.93V, not 2.64V. Verify the threshold and output type match your design before substituting.
