Product details
Overview
AD5100YRQZ-1RL7 from Analog Devices is a factory-programmed system management IC performing quad voltage monitoring (two 30 V high-voltage, two low-voltage) and watchdog supervision. It delivers shutdown control via SHDN (push-pull, V1MON/VREG-rail), reset control via RESET (push-pull, V3MON-rail), and fault detection across all four inputs. It operates from 6.0 V to 30 V supply and −40°C to +125°C, targeting automotive power sequencing and microprocessor supervision.
For engineers reviewing the AD5100YRQZ-1RL7 datasheet, AD5100YRQZ-1RL7 pinout, AD5100YRQZ-1RL7 application, or AD5100YRQZ-1RL7 equivalent, key selection criteria include its factory-programmed OV/UV thresholds (e.g., V1MON OV = 7.92–28.29 V), programmable shutdown hold/delay (0.07 ms–200 ms), I²C interface for dynamic override, eMOST-compatible high-voltage pinouts, and dual supervisory outputs with independent timing control.
Technical Context
The AD5100YRQZ-1RL7 integrates four independent monitoring channels: V1MON and V2MON support 30 V input ranges with shutdown and reset control, while V3MON (2.32–4.97 V) and V4MON (1.67–7.96 V) provide low-voltage reset-only supervision. Each channel uses comparators with 1.2–1.5% hysteresis and factory-programmed thresholds stored in OTP memory.
Its supervisory architecture includes a watchdog timer with selectable timeout (100 ms–2000 ms), manual reset (MR) with highest priority over other inputs, and dual output drivers: SHDN (push-pull, 13.5 mA sink, V1MON/VREG rail) and RESET (push-pull, V3MON rail, 3.2 mA sink). The I²C interface enables temporary register override without altering OTP settings.

FAQ
What is the primary function of the AD5100YRQZ-1RL7 in an automotive system?
The AD5100YRQZ-1RL7 serves as a factory-programmed quad-voltage supervisor that monitors battery voltage (V1MON), ignition status (V2MON), MCU core supply (V3MON), and diagnostic rail (V4MON) to generate coordinated SHDN and RESET signals. In automotive systems, it ensures safe power sequencing, prevents brownout-induced MCU crashes, and enables MOST network wake-up-all within −40°C to +125°C operation. Its 5 μA shutdown current and eMOST-compatible pinout make AD5100YRQZ-1RL7 ideal for always-on vehicle modules.
How does the AD5100YRQZ-1RL7 handle overvoltage and undervoltage conditions on the V1MON input?
The AD5100YRQZ-1RL7 uses two independent comparators on V1MON-one for overvoltage (OV) and one for undervoltage (UV)-each with 1.5% hysteresis. When V1MON exceeds the factory-programmed OV threshold (e.g., 12.00 V), SHDN activates after a programmable delay (t1SD_DELAY); when V1MON falls below the UV threshold (e.g., 6.00 V), SHDN asserts immediately. Both conditions also trigger RESET with matching timing. The AD5100YRQZ-1RL7 maintains ±2% threshold accuracy across −40°C to +125°C, ensuring reliable protection during load-dump or cold-cranking events.
Can the AD5100YRQZ-1RL7 be reprogrammed after manufacturing, or is it strictly one-time programmable?
The AD5100YRQZ-1RL7 features one-time programmable (OTP) memory for factory-set thresholds and timing parameters, but it also includes an I²C interface that allows temporary override of register values-including watchdog timeout (tWD), reset hold time (tRS_HOLD), and shutdown delay (t1SD_DELAY)-without altering the OTP contents. This means AD5100YRQZ-1RL7 supports field-adjustable behavior for validation or minor tuning, while retaining permanent, production-validated settings in OTP for reliability-critical deployments.
What are the key differences between the SHDN and RESET outputs of the AD5100YRQZ-1RL7?
The SHDN output of the AD5100YRQZ-1RL7 is a push-pull driver referenced to V1MON or internal VREG (up to 30 V), capable of sinking 13.5 mA, making it suitable for directly disabling external DC-DC converters or high-side FETs. The RESET output is also push-pull but rail-referenced to V3MON (typically 3.3 V or 5 V), with 3.2 mA sink capability-optimized for asserting microcontroller reset pins. Their timing is independently programmable: SHDN responds to V1MON/V2MON faults, while RESET reacts to V3MON/V4MON, WDI, or MR events, enabling staged system recovery in AD5100YRQZ-1RL7 designs.
Is the AD5100YRQZ-1RL7 pin-compatible with other members of the AD5100 family, such as AD5100YRQZ-0RL7?
Yes, the AD5100YRQZ-1RL7 shares identical pinout, package (16-lead QSOP), and electrical interface with other AD5100 variants including AD5100YRQZ-0RL7. The suffix "-1" denotes a specific factory-programmed configuration-such as default V1MON OV = 9.00 V, UV = 6.49 V, and tWD = 250 ms-while "-0" reflects different OTP settings (e.g., V1MON OV = 7.92 V, UV = 6.00 V). All AD5100YRQZ-xRL7 devices are mechanically and electrically interchangeable; only OTP content differs, requiring no PCB or firmware changes when substituting within the same package variant.
