Frequently Asked Questions
What is the reset threshold voltage of the TPS3828-50DBVT?
The TPS3828-50DBVT has a fixed reset threshold voltage of 4.55V. When the monitored 5.0V supply drops below this level, the active-low RESET output is asserted, holding the connected microcontroller or processor in reset until the supply recovers above the threshold.
What package does the TPS3828-50DBVT use, and how many pins does it have?
The TPS3828-50DBVT comes in a SOT-23-5 (5-pin small-outline transistor) package, also known as TSOP5. This compact surface-mount package measures approximately 2.9 x 1.6 mm, making it ideal for space-constrained PCB designs in consumer and industrial electronics.
What are typical applications for the TPS3828-50DBVT?
The TPS3828-50DBVT is typically used for power supply supervision in microcontroller-based systems, DSP boards, FPGAs, and communication modules. It ensures reliable reset during power-on sequences and brownout events, and is well-suited for industrial control, IoT gateways, handheld devices, and any application requiring a stable 5V supply monitor.
Can the TPS3828-50DBVT be used as a drop-in replacement for other voltage supervisor ICs?
The TPS3828-50DBVT is pin-compatible with many standard SOT-23-5 voltage supervisors that monitor a 5.0V rail with a similar reset threshold. Common alternatives in the same family include the TPS3828-33DBVT (3.3V version) and other single-channel supervisors with fixed thresholds. Always verify the threshold voltage and timing specifications before substitution.
