What are the key features of TPS3307-18MJG?
- 3-channel simultaneous voltage supervision enabling single-IC monitoring of multi-rail power supplies without discrete comparators
- Adjustable threshold detection allowing custom reset assert voltages for non-standard supply rails between 1.8 V and 5 V
- Ceramic glass-sealed DIP-8 package (JESD-30 R-GDIP-T8) qualified for military and high-reliability applications up to 125°C
- Active-low manual reset input providing controlled system initialisation from external logic or push-button
- RoHS-compliant lead-free marking (JESD-609 e0) meeting environmental compliance requirements
What is TPS3307-18MJG used for?
The TPS3307-18MJG supervises multi-rail power sequences in military, aerospace, and high-reliability embedded systems where all 3 supply rails must be above threshold before a processor or FPGA is released from reset. Industrial control boards use its adjustable threshold to monitor 1.8 V, 3.3 V, and 5 V rails simultaneously, reducing the number of discrete supervisor ICs from 3 to 1. Its ceramic-sealed package makes it suitable for mission-critical applications requiring operation across the full military temperature range of -55°C to +125°C without performance degradation.

Frequently Asked Questions
How many supply rails does the TPS3307-18MJG monitor, and what threshold flexibility does it offer?
The TPS3307-18MJG monitors 3 independent voltage rails simultaneously, each with an adjustable reset threshold configurable via external resistor dividers to detect undervoltage conditions on rails between 1.8 V and 5.5 V, covering mixed-voltage SoC power domains without additional comparator ICs.
What package does the TPS3307-18MJG use, and why is ceramic construction important in harsh environments?
The TPS3307-18MJG uses a ceramic glass-sealed DIP-8 package (JESD-30 R-GDIP-T8), which provides hermetic sealing to MIL-STD-883 standards, protecting the die against moisture, vibration, and thermal shock in military and aerospace applications operating from -55°C to +125°C where plastic packages would crack or absorb humidity.
In a multi-rail processor board using 1.8 V core, 3.3 V I/O, and 5 V analog rails, how does the TPS3307-18MJG simplify the reset circuit?
By integrating 3 voltage comparator inputs into one IC, the TPS3307-18MJG asserts a single active-low reset output only when all 3 rails are simultaneously above their respective thresholds, eliminating the AND-gate and 3 discrete supervisor ICs that would otherwise occupy 3× more PCB area and add 3× more failure-mode items to the FMEA.
What is the reset assertion delay of the TPS3307-18MJG, and how does this affect processor start-up sequencing?
The TPS3307-18MJG uses a fixed internal reset timeout delay that keeps the reset output asserted for a minimum period after all monitored rails cross their thresholds, ensuring the processor remains in reset for at least 200 ms during power-up to allow voltage regulators to fully settle before the CPU begins executing code.
When would an engineer select the TPS3307-18MJG over a single-channel reset IC in a space-constrained military design?
Designers choose the TPS3307-18MJG when 3 rails must each cross their thresholds before a system-critical FPGA or DSP releases reset, because a single-channel device would require 3 ICs plus external logic to AND the reset outputs — adding at least 4 components and 100 mm² of board space in a DIP-8 footprint that the TPS3307-18MJG already occupies.
