What are the key features of TPS37B010122DSKR?
- Wide 65 V input range with dual-channel window supervision detects both undervoltage and overvoltage faults on two rails simultaneously
- Programmable time-delay function filters transient glitches and prevents nuisance resets in noisy industrial and automotive environments
- Ultra-low quiescent current in a 10-pin SON package ideal for always-on monitoring from -40°C to 125°C
What is TPS37B010122DSKR used for?
The TPS37B010122DSKR is designed for industrial power supplies, motor drives, and telecommunications equipment where simultaneous monitoring of two high-voltage rails up to 65 V is required across the full -40°C to 125°C temperature range. Its adjustable window thresholds allow engineers to set precise undervoltage and overvoltage trip points tailored to each rail, while the built-in time-delay function prevents false fault assertions caused by transient load steps. The 10-pin SON package and low quiescent current make it well-suited for always-on supervisory circuits in automotive body-control and ADAS power-management designs.

Frequently Asked Questions
What is the maximum input voltage that TPS37B010122DSKR can safely monitor on each supervised rail?
The TPS37B010122DSKR supports input voltages up to 65 V on each supervised channel, making it directly applicable to 48 V automotive, 24 V industrial, and 36 V motor-drive power rails without external voltage dividers or additional protection components.
How does the programmable time-delay function in TPS37B010122DSKR reduce false fault events in noisy environments?
The integrated time-delay function requires a fault condition to persist for a user-set duration—typically configured with an external capacitor—before asserting the fault output. This masks sub-millisecond voltage dips caused by load transients on 48 V bus capacitors and prevents nuisance system resets in industrial motor-control and server power applications.
Over what temperature range can TPS37B010122DSKR operate, and which industrial or automotive grades does this cover?
The device is rated for operation from -40°C to 125°C, covering both the full industrial temperature range and the automotive AEC-Q100 Grade 1 temperature requirement. This makes it suitable for underhood automotive modules, outdoor industrial control panels, and telecom base-station power monitoring exposed to wide seasonal temperature swings.
How does dual-channel window supervision in TPS37B010122DSKR differ from a simple undervoltage supervisor?
A simple undervoltage supervisor asserts a fault only when the supply falls below a single lower threshold. The TPS37B010122DSKR monitors 2 independent channels and checks both a lower undervoltage threshold and an upper overvoltage threshold on each, asserting a fault for out-of-window excursions in either direction—providing protection against both sagging rails and overvoltage events from inductive load switching on the same bus.
