Key Features
- Window voltage detection with adjustable upper and lower thresholds catches both over-voltage and under-voltage faults on a single 1.2 V reference supply rail
- AEC-Q100 qualified for automotive applications with -40°C to 125°C junction temperature range and robust 6-WSON 1.5 mm x 1.5 mm package
- Open-drain output allows wired-OR fault signaling in multi-supervisor safety networks without additional logic components
Applications
TPS3703A4120DSERQ1 is used in automotive ADAS, powertrain ECUs, and infotainment modules where accurate window voltage monitoring of 1.2 V processor core supplies is required to detect both under-voltage brownouts and over-voltage faults. It protects microcontrollers and FPGAs in safety-critical automotive systems by asserting a fault flag whenever the monitored rail drifts outside the programmed voltage window. The compact 1.5 mm x 1.5 mm WSON package suits dense multi-supply monitoring boards where board space is limited.

Frequently Asked Questions
What voltage reference does TPS3703A4120DSERQ1 use and how is the detection threshold set?
TPS3703A4120DSERQ1 uses an internal 1.2 V reference with adjustable threshold resistor dividers to set both the upper and lower window voltage limits. This allows detecting supply deviations as small as ±1% on a 1.2 V core supply rail in precision automotive power management circuits.
How does window detection in TPS3703A4120DSERQ1 improve protection compared to a simple under-voltage supervisor?
Unlike a simple under-voltage supervisor that only detects low supply, TPS3703A4120DSERQ1 monitors both over-voltage and under-voltage conditions simultaneously. If the 1.2 V core rail rises above the upper threshold due to a regulator fault or falls below the lower limit, the open-drain output immediately asserts to trigger a system fault response.
What automotive qualification does TPS3703A4120DSERQ1 carry for vehicle safety systems?
TPS3703A4120DSERQ1 is AEC-Q100 Grade 1 qualified, covering junction temperatures from -40°C to 125°C, and meets automotive reliability screening requirements for powertrain, ADAS, and body control module designs. The AEC-Q100 Grade 1 certification ensures the device passes accelerated life testing at 125°C for 1000 hours.
How compact is the TPS3703A4120DSERQ1 WSON package for multi-rail monitoring applications?
The 6-pin WSON package measures only 1.5 mm x 1.5 mm, making TPS3703A4120DSERQ1 one of the smallest automotive voltage supervisors available. Multiple devices can be placed within a 1 cm² area to monitor 4-6 independent power rails in space-constrained ADAS processing modules.
