TPS3307-18DGNG4

Supervisors Overview

The TPS3307-18DGNG4 is a triple voltage supervisory circuit manufactured by Texas Instruments. It monitors three independent supply rails with fixed thresholds of 1.68 V and 2.93 V, alongside an adjustable threshold. The device features a push-pull output configuration supporting both active-high and active-low reset signals. It includes a manual reset input for system control and operates within a supply voltage range up to 6 V. The component is housed in an 8-pin MSOP package with a power pad, designed for surface-mount installation.

Supervisors Feature Summary

• Triple-channel voltage monitoring with two fixed thresholds and one adjustable threshold
• Configurable push-pull output providing active-high or active-low reset signals
• Manual reset input capability for external system control

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Processor board voltage monitoring
• Industrial control unit power integrity verification

Supervisors Procurement Notes

Verify the specific suffix DGNG4 against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Confirm availability as distribution listings may vary. Ensure the selected package matches the PCB footprint requirements. Cross-reference the threshold voltages with the design specifications before finalizing procurement.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltage levels is required. The adjustable threshold allows flexibility for custom rail monitoring. The push-pull output simplifies interface logic without requiring external pull-up resistors. Consider the MSOP package size for space-constrained designs requiring multiple supervision channels.
