Applications
The TPS3828-33DBVR is widely used in microcontroller and DSP-based systems to monitor supply voltage and generate a clean reset signal during power-up, power-down, or brownout events. It is commonly deployed in industrial control units, consumer electronics, and embedded computing boards where reliable processor supervision is critical. The integrated watchdog timer also makes it suitable for remote or unattended systems that require automatic recovery from software lockups.

Frequently Asked Questions
What is the reset threshold voltage of the TPS3828-33DBVR?
The TPS3828-33DBVR monitors a fixed 3.3V supply rail. It asserts the active-low RESET output when the monitored voltage drops below the preset threshold (typically 3.08V), holding the processor in reset until the supply recovers and a timeout period elapses, ensuring stable startup.
Does the TPS3828-33DBVR include a watchdog timer, and how does it work?
Yes, the TPS3828-33DBVR integrates a watchdog timer (WDT). The host processor must periodically toggle the WDI input to service the watchdog. If the WDI pin is not toggled within the watchdog timeout window, the device asserts RESET, forcing the processor to restart and recover from a software hang or fault condition.
What package does the TPS3828-33DBVR use and what are its dimensions?
The TPS3828-33DBVR is housed in a 5-pin SOT-23 (TSOP5/6) package with a body pitch of approximately 0.11 inches (2.8mm). This compact surface-mount package is ideal for space-constrained PCB layouts in portable and embedded applications.
What are common alternatives or substitutes for the TPS3828-33DBVR?
Common alternatives include the Texas Instruments TPS3823 series (with different timeout periods), the Maxim MAX823/MAX6323, and the Microchip MCP130. When selecting a substitute, verify the reset threshold voltage, watchdog timeout, output polarity (active-low vs. active-high), and pin-compatible package to ensure drop-in compatibility.
