Key Features
- Single-channel adjustable threshold voltage supervisor allows precise monitoring of any supply rail from 0.4 V upward using an external resistor divider
- Ultra-small 6-pin SOT-23 package with 0.4 mm pitch occupies less than 2 mm² of PCB area, enabling voltage supervision in space-constrained IoT and wearable modules
- Precision internal reference and low supply current make TPS3895ADRYT ideal for power-sequencing and brown-out detection in single-cell and low-voltage designs
Applications
TPS3895ADRYT monitors critical power rails in microcontroller-based systems and FPGAs to ensure a clean reset is issued whenever the supply drops below the programmed threshold. Its adjustable threshold supports 1.0 V, 1.8 V, 3.3 V, and custom core supply voltages common in industrial sensors, wireless modules, and handheld instruments. The device also works as a sequencing sentinel in multi-rail power trees where downstream logic must not start before the upstream regulator reaches its regulation point.

Frequently Asked Questions
How do you set the reset threshold of TPS3895ADRYT for a 1.8 V supply rail?
Two external resistors connected from the monitored supply to the SENSE pin and from SENSE to GND form a resistor divider. For a 1.8 V threshold with TPS3895ADRYT's internal reference of 0.4 V, the upper resistor is set to (1.8 V – 0.4 V) / (0.4 V / R_bottom), typically R_top = 700 kΩ and R_bottom = 200 kΩ. The 1% resistors limit threshold error to within ±18 mV of the 1.8 V target.
What reset timeout does TPS3895ADRYT assert after the supply recovers from an undervoltage event?
TPS3895ADRYT holds the reset output active for a minimum reset timeout period after the monitored voltage rises above the threshold. The timeout is set by an optional external capacitor on the CT pin, typically 100 nF yields approximately 100 ms to 200 ms delay, ensuring the supply has stabilized and the MCU's oscillator has started before the reset is deasserted.
Is TPS3895ADRYT a suitable alternative to a fixed-threshold supervisor when monitoring a 3.3 V DDR SDRAM power supply?
Yes. Where a fixed-threshold device monitors only the standard 3.3 V ± 5% window (3.135 V to 3.465 V), TPS3895ADRYT can be programmed for a tighter ±2% window (3.234 V to 3.366 V) to catch supply droops that fall within the JEDEC DDR3L VDD tolerance but may still cause data corruption in high-speed memory interfaces at 1600 Mbps or above.
