What are the key features of TPS3103E12DBVR?
- Ultra-low quiescent supply current voltage supervisor with fixed threshold monitoring for reliable system reset
- 2-channel supervisory circuit in a compact 6-pin TSOP6 package for space-constrained designs
- RoHS-compliant plastic/epoxy TSOP6 (R-PDSO-G6) package with 0.95 mm pitch for fine-pitch SMT assembly
What is TPS3103E12DBVR used for?
The TPS3103E12DBVR is used in microprocessor and microcontroller reset circuits where accurate low-voltage supply monitoring is critical for preventing brownout-related system failures. Its ultra-low supply current makes it ideal for battery-powered IoT sensors, wearable devices, and energy-harvesting systems that must monitor supply rails at near-minimum operating voltages. The 2-channel configuration allows simultaneous supervision of two power rails, simplifying supervisory circuit design in dual-supply embedded systems.

Frequently Asked Questions
What voltage threshold does the TPS3103E12DBVR monitor and is it user-adjustable?
The TPS3103E12DBVR uses a fixed monitoring threshold — it is not adjustable — making it a plug-in solution for systems with a known supply voltage target; its low supply voltage capability allows it to operate and monitor voltages in the range suitable for low-power microcontrollers and sensors running from coin cells or energy-harvesting sources.
How does the TPS3103E12DBVR support dual-rail monitoring in embedded systems?
With 2 monitoring channels integrated into a single 6-pin TSOP6 package, the TPS3103E12DBVR can simultaneously supervise two separate power supply rails, generating a reset signal when either rail drops below its threshold, reducing the component count needed for dual-supply reset circuits in microcontroller-based IoT and wearable designs.
Why is ultra-low supply current important for the TPS3103E12DBVR in battery-powered applications?
In battery-powered devices such as wireless sensors or wearables, the voltage supervisor must consume minimal quiescent current to avoid draining the battery during standby; the TPS3103E12DBVR's ultra-low supply current ensures the supervisory function remains active for the device's intended battery life, which could span months or years from a coin cell or small lithium battery.
What package does the TPS3103E12DBVR use and how does it fit into a compact PCB design?
The TPS3103E12DBVR is housed in a 6-pin TSOP6 surface-mount package (R-PDSO-G6) with a 0.95 mm lead pitch and body dimensions of approximately 2.9 mm × 1.6 mm, making it one of the smallest footprints available for a 2-channel voltage supervisor and well-suited for highly miniaturized PCB designs in wearables and IoT sensor nodes.
