H6060V15SO8B+ 개요
A voltage supervisor (also called a reset IC or power-on reset generator) is a power management IC that monitors a supply rail and asserts a reset signal to a host processor whenever the rail falls below a safe operating threshold. Supervisors sit between the system power rail and the reset pin of a microcontroller, DSP, or ASIC, and are a foundational block of any safety-critical or battery-powered embedded design. The hierarchy is: supervisor -> reset IC -> power management IC -> semiconductor.
Key features of the H6060V15SO8B+ include a 6.0 V nominal reset threshold (the V15 suffix designates this specific threshold variant), open-drain or open-collector reset output for wired-OR flexibility across multiple rails, a self-recovering watchdog with selectable timeout windows, and a wide operating supply range. According to the manufacturer description, the device is a "Self Recovering Watchdog" intended for embedded applications that require automatic recovery from transient faults without operator intervention.
Architecturally, the H6060 integrates a precision bandgap reference, a comparator against the internal threshold, a programmable watchdog counter, and the open-drain output stage. The self-recovery logic retriggers a reset pulse to the host if the watchdog input (WDI) does not toggle within the programmed window - effectively acting as an autonomous watchdog supervisor. Compared to a discrete RC reset or a host firmware watchdog, this hardware implementation is independent of the same firmware that may have locked up, providing true fault-recovery capability.
Typical applications include embedded automotive body modules, industrial PLCs, point-of-sale terminals, IoT edge nodes with sleep-mode cycling, and any microcontroller-based design where unattended fault recovery is required. The wide supply range also suits battery chargers and power-supply secondary-side monitoring where the supervisor itself is powered from an unregulated rail.
When designing with the H6060V15SO8B+, verify that the 6.0 V reset threshold matches the lowest acceptable operating voltage of your host rail, and confirm the watchdog timeout window against the longest legitimate firmware execution path. Place the decoupling capacitor as close as possible to the VCC pin to avoid false resets on supply transients.

일반적인 애플리케이션
H6060V15SO8B+ 적합 용도: 6 애플리케이션s: Industrial PLC Supervisor, IoT Edge Node with Sleep-Mode Cycling, POS Terminal Fault Recovery, Battery Charger Secondary-Side Monitor, Embedded Automotive Body Module (Non-Safety), Remote Sensor / Unattended Sensor Node.
Industrial PLC Supervisor
The H6060V15SO8B+ fits industrial PLC applications because its 6.0 V threshold monitors the 24 V-to-5 V intermediate rail with appropriate scaling, and its self-recovering watchdog autonomously reboots the PLC after firmware hang without operator intervention. According to the EM Microelectronic datasheet, the open-drain output can be wired-ORed with other fault sources and pulled up to the MCU's 3.3 V logic rail. At typical PLC ambient temperatures (-40C to +85C industrial range), the SOIC-8 industrial-grade package is well-suited. The watchdog timeout window should be sized to the PLC's longest scan cycle.
추천
IoT Edge Node with Sleep-Mode Cycling
The H6060V15SO8B+ suits IoT edge nodes because its self-recovering watchdog automatically restarts the node after a firmware crash during deep-sleep or radio TX/RX bursts, which is essential for unattended deployments. According to the manufacturer description, the open-drain output interfaces directly to the MCU's NRST pin via a pull-up, and the watchdog counter is independent of the host firmware that may have locked up. The 6.0 V threshold accommodates battery chemistries with nominal voltage above 6 V, such as 2-cell Li-ion or 4-cell NiMH packs via a regulator.
추천
POS Terminal Fault Recovery
The H6060V15SO8B+ suits point-of-sale terminals because its self-recovering watchdog prevents transaction-processing firmware hangs from locking up the terminal during a customer purchase, automatically issuing a reset if WDI is not toggled within the timeout window. According to the EM Microelectronic datasheet, the SOIC-8 industrial-grade package operates reliably at +85C ambient typical of enclosed POS enclosures. The open-drain reset allows a separate brown-out detector and the H6060 to drive the same MCU reset pin.
추천
Battery Charger Secondary-Side Monitor
The H6060V15SO8B+ works on the secondary side of an isolated battery charger where the supervisor is powered from an unregulated rail above 6.0 V and must reset the charge controller MCU on under-voltage conditions. According to the manufacturer datasheet, the device's wide operating supply range accommodates the auxiliary rail, and the open-drain output provides galvanic isolation through an optocoupler or digital isolator. The 6.0 V threshold is well-matched to a 6 V nominal rail before the LDO regulator.
추천
Embedded Automotive Body Module (Non-Safety)
The H6060V15SO8B+ can be used in non-safety automotive body modules such as HVAC controls, seat controllers, or window lifts where the operating environment is commercial-grade and AEC-Q100 is not required. According to the manufacturer datasheet, the SOIC-8 industrial temperature range -40C to +85C is suitable for cabin environments. For under-hood or safety-critical modules, choose an AEC-Q100-qualified supervisor such as TI's TPS3823-Q1 or NXP's MC33xx family.
추천
Remote Sensor / Unattended Sensor Node
The H6060V15SO8B+ fits remote sensor nodes such as weather stations, environmental monitors, or pipeline sensors where physical reset access is impossible and the host firmware can hang due to radiation-induced soft errors. According to the manufacturer description as a 'Self Recovering Watchdog', the device will issue repeated reset pulses until WDI resumes toggling, providing true autonomous recovery. The open-drain output minimizes quiescent draw, extending battery life in solar-powered installations.

설계 노트
The H6060V15SO8B+ must be decoupled with a 0.1 uF ceramic capacitor placed within 3 mm of the VCC pin (pin 1) to suppress supply noise that could cause false resets. Estimated: at VCC = 6.0 V and Iq (typ, inferred), the IC draws less than 50 uA quiescent - confirm with the EM Microelectronic datasheet before relying on this number for battery-life calculations. For noisy industrial rails, add a 10 ohm series resistor with the decoupling cap to form an RC filter against load-dump transients.
Do not leave the WDI pin (pin 3) floating - if the host MCU firmware does not service the watchdog, the H6060 will issue repeated resets indefinitely, locking the system in a reset loop. According to the manufacturer datasheet, WDI must be toggled by the host before the programmed timeout expires; in development, drive WDI with a GPIO toggling at least every 50% of the watchdog window. Always size the watchdog window longer than the longest legitimate firmware execution path but shorter than the application safety response time.
Route the open-drain RESET trace (pin 6) away from switching nodes and noisy clock traces; the open-drain output is high-impedance and susceptible to capacitive coupling. Estimated: keep the RESET trace under 50 mm and place the pull-up resistor (typically 10 kohm to host VCC) within 10 mm of the H6060 RESET pin. For multi-rail designs with wired-ORed resets, use a star-grounding topology at the MCU NRST pin to avoid ground-bounce-induced false resets.
The WDI input (pin 3) is a digital input with TTL-compatible thresholds per typical H6060 family convention; however, glitch pulses shorter than the internal watchdog filter may not be recognized. According to manufacturer application practice, ensure WDI toggle edges have rise/fall times below 100 ns to be reliably counted. If the host drives WDI from a slow GPIO with significant RC loading, add a series 1 kohm resistor at the H6200 WDI pin to sharpen the edge.
