uP supervisors & POR/BOR, programmable multi-rail/windowed monitors, reset trees & debounce, RTC switchover, watchdog timers, sequencing & voting logic, telemetry & reset causes, port co-protection, application-focused parts, and design hooks.
Supervisors & Reset ICs
µP Supervisor / Reset IC
Precision UV/OV thresholds, push-pull or open-drain reset, delay/debounce for tricky power edges.
Multi-Rail Programmable Supervisor
Per-rail/window thresholds with I²C/PMBus config, PG aggregation and power-fail tagging.
Windowed Voltage Supervisor
Upper/lower windows with hysteresis for drift/jitter immunity; analog/DAC-settable levels.
POR / Brown-Out Detector
Low-Iq accurate trip; works with fast/slow ramps, pre-bias and slope timing.
Reset Tree & Fanout Buffer
Fanout buffers with wide-level compatibility to manage reset sequencing & dependencies.
Push-Button / Manual Reset Debounce
Programmable debounce/long-press; safe path from key to system reset.
RTC w/ Supervisor & Switchover
Main/backup auto switchover, low leakage, power-fail timestamp and wake sources.
Watchdog Timers
Simple Watchdog Timer
Independent timebase with feed window, reset/IRQ options and low power.
Windowed Watchdog
Upper/lower timing windows detect wrong feeds; latch fault cause before reset.
Safety Watchdog (ASIL/SIL)
Independent clock/power domain, fault-injection self-tests and fail-safe outputs with coverage reports.
Clock Monitor / Missing-Pulse
Detects crystal failure/runaway and frequency drift; auto switches to backup clock.
Multi-Channel / Partitioned WDT
Independent supervision per core/domain with isolation and partition resets.
Sequencing & Timing
Power Sequencer
Defines up/down order, dependencies/trackers, slew control and fault rollback.
Reset Delay / One-Shot
Accurate delays for pre-WDT grace, reset stretch/compress.
Power-Good Logic & Voting
Combine PGs with 1oo2/2oo3 voting, interlocks and bypass paths.
Remote-Sense Supervisor
Differential detect with cable-drop compensation to improve long-line PoL stability.
Monitoring & Telemetry
V/I/T System Monitor
Multi-channel ADC with alerts, emergency derating and black-box events.
PMBus/SMBus Power Monitor
Telemetry registers, alert masks and threshold scripts for field tuning.
Reset Cause & Event Logger
Tags BOR/WDT/EXT sources with timestamps and monotonic counters.
Port & Interface Co-Protection
Upstream/Downstream PG Interlock
Coordinates with eFuse/ideal-diode for cascade isolation and fast shut-down.
LDO/DC-DC Co-Design Supervisor
Match steady-state/transient thresholds, pre-bias start and soft-start alignment.
Security-Coupled Supervisor
Reset-lock order, key power-up windowing and tamper/zeroize triggers.
Specialties & Applications
Automotive Supervisor (Cranking/Load Dump)
Wide VIN/temp with ISO-7637 immunity and ASIL interfaces.
Intrinsic-Safety / Isolated Supervisor
Isolation-aware thresholds, energy-limit voting and safe-state defaults.
Server-Class Sequencing & Supervisor
10–20+ rails with PMBus, redundancy, and FRU logging.
RF/Clock Rail Supervisor
High-frequency PSRR focus with phase-noise-friendly thresholds and PLL/VCO drop protection.
Imager/AFE Rail Supervisor
Soft clamps, power-up order & bias conservation to avoid black-level drift.
Design Hooks
Threshold & Tolerance
Accuracy class, temp-drift, divider errors and proper hysteresis sizing.
Glitch & Debounce
POR glitch filtering, minimum-valid-time and EMI-robust design.
Reset Polarity & Levels
Push-pull vs open-drain, active-high/low and cross-domain pull-up strategy.
Clock Independence
Independent RC/XTAL for WDT, common-cause isolation and redundant timebases.
Fail-Safe & Derating
Default safe states, timeout/mismatch voting and temp/lifetime derating.
Layout & Grounding
Keep threshold pins quiet; split-ground/star returns and crosstalk-proof reset lines.
Self-Test & Diagnostics
Threshold injection/sweeps, WDT fault-injection, reset-cause readback and production hooks.
