LM3704XBMM-463 Texas Instruments Integrated Circuit (Small Outline Packages) In Stock
Texas Instruments LM3704XBMM-463 is a single-channel voltage supervisor and reset IC monitoring a 4.63 V threshold with manual reset capability and power-fail input. It generates a system reset signal when supply voltage drops below the preset 4.63 V threshold to prevent processor glitching. Packaged in a 10-pin TSSOP for compact space-constrained embedded system power management.

What are the key features of LM3704XBMM-463?
- Single-channel voltage supervisor with fixed 4.63 V reset threshold for 5 V rail monitoring
- Manual reset input allowing external push-button initiated system reset events
- Power-fail input monitoring a secondary rail before the main reset assertion occurs
- 10-pin TSSOP package enabling minimal PCB footprint in dense embedded designs
- Fixed-threshold non-adjustable architecture reducing external component count to near zero
What is LM3704XBMM-463 used for?
The LM3704XBMM-463 is used in embedded microprocessor and DSP systems operating from a 5 V rail where reliable power-on reset and brownout protection at 4.63 V are required. Its manual reset input supports front-panel reset buttons in industrial controllers, network routers, and set-top boxes without additional glue logic. Consumer electronics, automotive infotainment modules, and communication equipment also rely on this device to ensure orderly startup and shutdown during power supply transitions.

Frequently Asked Questions
At what voltage threshold does LM3704XBMM-463 assert a system reset signal?
The LM3704XBMM-463 asserts its reset output when the monitored supply voltage falls below the fixed 4.63 V threshold, protecting 5 V microprocessors and DSPs from operating in an undefined state during brownout or power-up ramp conditions below that level.
Does LM3704XBMM-463 support a manual reset input, and how is it used in industrial equipment?
Yes, it includes a dedicated manual reset input that accepts an active-low signal from an external push-button or system controller, enabling forced system reset at any time independent of supply voltage, which is essential for field-service recovery in industrial PLCs and embedded controllers.
How does LM3704XBMM-463 fit into a compact embedded board given its 10-pin TSSOP package?
The 10-pin TSSOP package measures approximately 3 mm x 4.4 mm with 0.5 mm pitch, occupying minimal PCB area while providing reset supervision, manual reset, and power-fail monitoring for a 5 V microprocessor system without requiring any external resistor dividers for the 4.63 V threshold.
When is LM3704XBMM-463 preferable to an adjustable-threshold supervisor in a fixed 5 V system design?
For a fixed 5 V rail design where the reset threshold is always 4.63 V, using LM3704XBMM-463 eliminates 2 external resistors needed by adjustable supervisors, reduces BOM cost, removes threshold tolerance error from resistor mismatch, and simplifies PCB layout in space-constrained 10-pin footprints.
