Product details
Overview
AD5100YRQZ-0 from Analog Devices is a factory-programmed system management IC for automotive-grade voltage supervision and watchdog control. It integrates four independent monitoring channels (V1MON/V2MON/V3MON/V4MON), dual shutdown/reset outputs, I²C interface, and OTP-configured thresholds - enabling precise power-up sequencing, fault detection, and external device shutdown in 12 V/24 V battery systems.
For engineers reviewing the AD5100YRQZ-0 datasheet, AD5100YRQZ-0 pinout, AD5100YRQZ-0 application, or AD5100YRQZ-0 equivalent, this page delivers verified specifications including programmable 6–30 V high-voltage monitoring, −40°C to +125°C operation, 5 μA shutdown current, QSOP-16 package mapping, and confirmed alternatives for automotive supervisory IC selection.
Technical Context
The AD5100YRQZ-0 implements dual high-voltage comparators (V1MON/V2MON) with 1.5% hysteresis and factory-programmed OV/UV/on/off thresholds, plus two low-voltage inputs (V3MON/V4MON) supporting 1.67–7.96 V reset control. Its watchdog circuit offers selectable timeout modes (standard/advance/floating), while the I²C interface enables dynamic register override of OTP settings.
It features eMOST-compatible high-voltage input shielding, rail-selectable SHDN output (V1MON or internal VREG), push-pull RESET referenced to V3MON, and open-drain SHDNWARN/V4OUT outputs - all coordinated via an integrated fault detection logic block that prioritizes MR > WDI > VxMON events.

Use Scenario: Real-time monitoring of 12 V/24 V vehicle battery during cold cranking, load dump, and alternator regulation. IC Role / Device Role / Timing Role: V1MON tracks battery voltage; SHDN disables non-critical loads during UV/OV faults; SHDNWARN triggers backup memory write before shutdown. Use Value: Prevents ECU corruption during voltage transients by asserting RESET within 60 μs of fault detection and holding it for programmable 0.1–200 ms. |
Use Scenario: Controlled power-up of head unit subsystems (DSP, display, tuner) after ignition-on and stable 5 V rail establishment. IC Role / Device Role / Timing Role: V2MON senses ignition rise; V3MON verifies 3.3 V core supply; RESET releases processors only after both conditions met. Use Value: Eliminates boot failures caused by improper sequencing - ensures DSP initializes before audio codec, preventing pop/noise on startup. |
| Diagnostic Fan Control | Network Equipment Supervision |
|
Use Scenario: Thermal management of automotive telematics module using battery voltage as proxy for ambient temperature. IC Role / Device Role / Timing Role: V4MON monitors scaled-down battery voltage; V4OUT generates PWM signal to drive cooling fan at variable speed. Use Value: Enables analog-free fan control with 10 kHz max frequency - avoids discrete op-amp circuits and reduces BOM count by 3 components. |
Use Scenario: Fault protection for telecom line cards operating from −48 V DC supplies with local 3.3 V/5 V regulators. IC Role / Device Role / Timing Role: V1MON monitors −48 V-derived 12 V intermediate rail; SHDN cuts power to FPGA if undervoltage persists beyond 200 ms. Use Value: Achieves <100 ms fault-to-shutdown latency - prevents FPGA configuration corruption during brownout events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervision and watchdog applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6816ESE+ | Single-channel 5 V supervisor; no I²C interface; fixed thresholds; no high-voltage inputs | Limited to low-voltage digital rails; cannot monitor battery directly | Select only for simple 3.3 V/5 V microcontroller reset where battery supervision is handled externally |
| TPS3808G33DBVR | Dual-supply monitor (3.3 V + adjustable); no watchdog; no high-voltage capability; SOT-23-6 package | Designed for point-of-load monitoring, not system-level battery management | Choose when space-constrained PCBs require single-rail reset with 2% threshold accuracy, but no shutdown control needed |
Compared with MAX6816ESE+ and TPS3808G33DBVR, AD5100YRQZ-0 uniquely combines quad-voltage monitoring (including 30 V capable inputs), programmable shutdown timing, I²C configurability, and automotive temperature range - making it the only option for integrated battery-level supervision in harsh-environment ECUs.

FAQ
What is the primary function of the AD5100YRQZ-0 in automotive systems?
The AD5100YRQZ-0 serves as a factory-programmed supervisory IC that monitors up to four voltage rails-including 6–30 V battery inputs-and asserts SHDN and RESET signals to protect downstream electronics during overvoltage, undervoltage, or watchdog timeout events. In automotive applications, AD5100YRQZ-0 ensures reliable power-up sequencing, graceful shutdown during cranking, and fault-isolated reset generation for ECUs and infotainment modules.
Does the AD5100YRQZ-0 support I²C reprogramming of its factory-set thresholds?
Yes, the AD5100YRQZ-0 includes an I²C-compatible interface that allows temporary override of OTP-programmed thresholds and timing parameters during operation. While the base configuration is permanently stored in one-time programmable memory, AD5100YRQZ-0 supports dynamic adjustment of registers such as reset hold time and watchdog timeout via SDA/SCL-enabling field calibration and adaptive system tuning without hardware changes.
What is the maximum input voltage rating for the V1MON pin on the AD5100YRQZ-0?
The V1MON pin on the AD5100YRQZ-0 has an absolute maximum rating of +33 V and operates across a functional range of 6.0 V to 30 V. This allows direct connection to 12 V and 24 V automotive battery rails, including transient spikes up to 33 V, without external clamping circuitry. The AD5100YRQZ-0 maintains ±2% threshold tolerance over −40°C to +125°C for reliable operation under load dump and cold-cranking conditions.
How does the AD5100YRQZ-0 handle manual reset requests?
The AD5100YRQZ-0 accepts manual reset via the MR pin (Pin 5), which is active-low and features 100 ns deglitching. When asserted, MR forces RESET low with highest priority-overriding watchdog timeouts, voltage faults, and VxMON events. The AD5100YRQZ-0 requires a minimum 1 μs pulse width and interprets logic levels relative to V3MON (0.3×V3MON low, 0.7×V3MON high), ensuring compatibility with diverse microcontroller I/O standards.
Is the AD5100YRQZ-0 pin-compatible with other members of the AD5100 family?
No, the AD5100YRQZ-0 is a specific factory-programmed variant and shares the same QSOP-16 pinout as other AD5100 devices (e.g., AD5100YRQZ-1), but its OTP configuration-including V1MON OV/UV thresholds, V2MON on/off points, and tRS_HOLD timing-is unique to the -0 suffix. While mechanical and electrical pin compatibility exists, functional behavior differs due to programmed settings; substitution requires verification of threshold alignment and timing requirements against the target application.
