Applications
The TPS3899DL15DSER monitors 1.5 V power rails in embedded systems, asserting a reset signal when supply voltage drops below the fixed threshold. It is used in portable consumer electronics, IoT nodes, and industrial microcontroller boards where orderly power-on reset and manual reset are required. The compact 6-pin SOT-23 package suits space-constrained designs with supply voltages near 1.5 V.

Frequently Asked Questions
What reset threshold does TPS3899DL15DSER monitor and does it support a programmable reset delay?
The TPS3899DL15DSER monitors a fixed 1.5 V threshold and asserts the reset output when the supply drops below that level. It supports a programmable reset delay set by an external capacitor, allowing designers to fine-tune hold-off time from microseconds to milliseconds to accommodate slow-ramping power rails in embedded microcontroller systems.
Does TPS3899DL15DSER include a manual reset pin and how is it useful in system designs?
Yes, TPS3899DL15DSER includes a manual reset input that allows a pushbutton or external logic to force a system reset independent of voltage supervisor activity. This is valuable in industrial and consumer electronics panels where operators must trigger a hardware reset without cycling power, all within a compact 6-pin SOT-23 package.
When should a designer choose TPS3899DL15DSER over a supervisor with an adjustable threshold?
TPS3899DL15DSER is the right choice for fixed 1.5 V rail supervision where threshold accuracy and design simplicity are prioritized over flexibility, as it eliminates the external resistor divider required by adjustable-threshold supervisors. The 6-pin SOT-23 footprint reduces BOM cost and PCB area in single-supply IoT and portable battery-powered applications with 1.5 V core rails.
