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.
