What are the key features of TPS37A010122DSKR?
- Dual-channel under/overvoltage supervision monitors 2 independent supply rails simultaneously in a single 10-pin package
- Fully adjustable threshold resistor network enables precise voltage window detection for any rail voltage
- Active-low open-drain output with programmable reset delay prevents false resets during supply ramp-up sequences
- 10-pin WSON no-lead package with 1.5 mm x 2 mm footprint minimizes PCB area in space-constrained designs
What is TPS37A010122DSKR used for?
TPS37A010122DSKR is used in multi-rail power management systems to monitor 2 supply voltages simultaneously and assert a reset or fault signal when either voltage falls outside the programmed window. Its adjustable threshold pins allow monitoring of 1.8 V, 3.3 V, 5 V, or any custom rail by choosing appropriate external resistor dividers. The device is suited for industrial microcontroller systems, communications equipment, and battery-powered IoT nodes where detecting both undervoltage and overvoltage faults on 2 channels is required for safe startup and fault protection.

Frequently Asked Questions
How many supply rails can TPS37A010122DSKR monitor simultaneously and what fault types does it detect?
TPS37A010122DSKR monitors 2 independent supply rails simultaneously, detecting both undervoltage and overvoltage conditions on each channel. The adjustable threshold inputs allow setting a precise voltage window for each rail using external resistor dividers, and the device asserts a fault output when any monitored voltage moves outside its programmed 2-channel window, protecting downstream processors and analog circuits from operating outside safe supply limits.
What external components are needed to set the voltage monitoring threshold for TPS37A010122DSKR?
Setting a monitoring threshold on TPS37A010122DSKR requires 2 external resistors per channel forming a resistor divider between the supply rail and the threshold input pin. For example, monitoring a 3.3 V rail with a 10% window uses a 100 kΩ and 33 kΩ divider to set the nominal threshold at the internal 1.2 V reference level. No capacitors or active components are required for basic threshold setting, keeping the total BOM for 2-channel monitoring to 4 resistors plus the IC.
What package does TPS37A010122DSKR use and how does it compare to similar supervisors in larger packages?
TPS37A010122DSKR is housed in a 10-pin WSON no-lead package measuring approximately 1.5 mm x 2 mm with 0.5 mm pin pitch, which is significantly smaller than 8-pin SOT-23 or 14-pin SOIC supervisors. This compact footprint enables the 2-channel overvoltage and undervoltage supervisor to fit in space-constrained IoT and wearable designs, while the no-lead construction provides better thermal and electrical performance than leaded alternatives at the same power level.
How does TPS37A010122DSKR handle supply ramp-up to avoid false reset assertions during power-on?
TPS37A010122DSKR includes a programmable reset timeout delay that holds the fault output asserted for a defined period after the monitored supply crosses its threshold, typically configurable from 1 ms to several hundred milliseconds using an external capacitor on the delay pin. This prevents false system resets caused by normal power supply ramp rates slower than 10 V/ms, ensuring the 2 monitored rails have fully stabilized before the supervisor releases the reset signal to downstream microcontrollers or FPGAs.
