Product details
Overview
ISL88002IE17Z-T from Renesas Electronics is an ultra-low-power 3-lead voltage supervisor IC with open-drain active-low reset output, 1.67V fixed threshold, ±1.2% accuracy, 160nA supply current, and operation down to VDD = 1V. It monitors single power rails in battery-powered microcontroller systems requiring reliable brownout detection and power-on reset.
For engineers reviewing the ISL88002IE17Z-T datasheet, ISL88002IE17Z-T pinout, ISL88002IE17Z-T application, or ISL88002IE17Z-T equivalent, this page delivers verified specifications, package mapping, functional pin definitions, real-world use cases, and validated alternative options for industrial and portable embedded designs.
Technical Context
The ISL88002IE17Z-T integrates a precision bandgap reference, comparator with hysteresis, and POR circuitry to assert reset when VDD falls below 1.67V or rises above it after power-up. Its open-drain RST output requires an external pull-up resistor (5kΩ–100kΩ) and remains valid down to 1V supply, enabling robust supervision of low-voltage logic rails.
It operates across –40°C to +85°C, consumes only 160nA at 1.8V/1.67V, and features 190ms typical POR timeout (tPOR), 15µs propagation delay (tRPD), and <1% VTH hysteresis - all optimized for minimal board space and maximum system reliability in SC-70 packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 1.67V ±1.2% - precisely monitors 1.8V supply rails with guaranteed trip margin under temperature and aging. |
| Supply Current | 160nA typical at 1.8V - enables multi-year battery life in always-on supervisory applications. |
| POR Timeout | 190ms typical - holds reset long enough for FPGA configuration, oscillator stabilization, and register initialization. |
| Operating Voltage Range | 1.8V to 2.75V - supports core logic supplies while asserting reset down to VDD = 1V for fail-safe behavior. |
| Output Type | Active-low open-drain - allows wired-OR reset bus sharing and flexible voltage-level translation via external pull-up. |
| Temperature Range | –40°C to +85°C - qualified for industrial-grade embedded systems without derating. |
| Hysteresis | 1% of VTH - prevents noise-induced reset chatter during marginal supply conditions. |
Pinout & Package
ISL88002IE17Z-T is housed in a Pb-free 3-lead SC-70 package (JEDEC MO-203AA, pkg drawing P3.049), measuring 2.20mm × 1.35mm × 0.95mm, with gull-wing leads and 0.65mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for internal circuitry and reset comparator; must be connected to system ground plane for stable threshold accuracy. |
| 2 | RST | Active-low open-drain reset output; sinks current when asserted; requires external pull-up resistor (5kΩ–100kΩ) to host supply rail. |
| 3 | VDD | Power supply input and monitored voltage node; supplies internal circuitry and serves as the sensed rail for 1.67V threshold detection. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 160nA enables decades-long operation on coin-cell batteries in IoT sensors and wearables. |
| ±1.2% threshold accuracy | Eliminates need for external calibration or trimming resistors in production test flow. |
| 1V minimum operating voltage | Ensures reset assertion remains valid even during deep brownout or battery depletion events. |
| No external components required | Reduces BOM count and PCB area - only pull-up resistor needed for RST, no capacitors or dividers. |
| Immunity to supply transients | Hysteresis and internal filtering prevent false resets caused by switching noise or load dump spikes. |
Applications
| Portable Medical Sensors | Industrial PLC I/O Modules |
|---|---|
Use Scenario: Continuous glucose monitor powered by CR2032 battery with 1.8V MCU and analog front-end. IC Role / Device Role / Timing Role: Monitors 1.8V supply and asserts open-drain reset to hold MCU in reset until voltage stabilizes post-battery insertion or wake-up. Use Value: Prevents corrupted sensor readings or EEPROM writes during undervoltage; 160nA draw extends battery life beyond 5 years. |
Use Scenario: DIN-rail mounted I/O module with isolated 1.8V digital logic rail derived from 24V field supply. IC Role / Device Role / Timing Role: Supervises 1.8V rail generated by DC-DC converter; triggers system-wide fault latch on brownout via shared RST bus. Use Value: Guarantees deterministic startup and safe shutdown during factory power fluctuations; ±1.2% accuracy avoids nuisance trips in noisy industrial environments. |
| Smart Meter Communication Units | Low-Power Wireless Gateways |
Use Scenario: NB-IoT modem section powered from 1.8V LDO, co-located with energy metering SoC. IC Role / Device Role / Timing Role: Provides POR and continuous voltage monitoring for modem subsystem; RST tied to SoC's external reset input. Use Value: Ensures modem firmware never executes with unstable supply; 190ms tPOR aligns with RF crystal startup time. |
Use Scenario: BLE/Wi-Fi gateway using 1.8V core voltage for RF transceiver and baseband processor. IC Role / Device Role / Timing Role: Detects 1.8V rail collapse during hot-swap battery replacement or transient ESD event. Use Value: Open-drain output allows direct connection to multi-rail reset supervisor bus; 1V min VDD operation ensures fail-safe reset assertion even during fast droop. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809SEUR+T | 1.68V threshold, ±2.5% accuracy, 1.2µA supply current, SOT-23-3 package. | Higher quiescent current limits battery lifetime; looser accuracy increases risk of premature reset in tight-margin 1.8V systems. | Select when legacy footprint compatibility with MAX809 family is required and power budget allows >7× higher current draw. |
| TPS3801K33DBVR | 1.67V threshold, ±0.5% accuracy, 350nA supply current, SOT-23-3 package, push-pull output. | Push-pull output eliminates need for external pull-up but prevents wired-OR reset bus sharing; tighter accuracy adds cost. | Select when absolute threshold precision is critical and system architecture uses dedicated reset lines per IC. |
Compared with MAX809SEUR+T and TPS3801K33DBVR, ISL88002IE17Z-T delivers the lowest power consumption (160nA), best-in-class threshold accuracy (±1.2%) for its class, and open-drain flexibility - making it optimal for space-constrained, battery-sensitive, and multi-device reset-bus architectures.

FAQ
What is the exact reset threshold voltage of the ISL88002IE17Z-T and how accurate is it?
The ISL88002IE17Z-T has a nominal reset threshold of 1.67V with ±1.2% accuracy over –40°C to +85°C. At +25°C, the typical value is 1.670V, with min/max bounds of 1.650V and 1.690V. This accuracy is factory-trimmed and does not require external calibration, ensuring consistent performance across production lots and temperature ranges.
Does the ISL88002IE17Z-T require any external components to operate?
No, the ISL88002IE17Z-T requires no external passive components for basic operation. Only an external pull-up resistor (5kΩ–100kΩ) on the RST pin is needed due to its open-drain output configuration. No capacitors, resistors, or voltage dividers are necessary for threshold setting, timing, or filtering - simplifying layout and reducing BOM cost.
Can the ISL88002IE17Z-T supervise power rails below 1.8V?
Yes - the ISL88002IE17Z-T is specified to operate and assert reset down to VDD = 1V, even though its recommended supply range is 1.8V to 2.75V. This ensures fail-safe reset behavior during deep brownout or battery depletion, where the monitored 1.8V rail may sag below nominal before complete failure.
What is the power-on reset timeout duration for the ISL88002IE17Z-T?
The ISL88002IE17Z-T provides a typical power-on reset timeout (tPOR) of 190ms, with a guaranteed range of 140ms to 260ms over temperature. This interval ensures sufficient hold time for microcontroller clock stabilization, FPGA configuration loading, and peripheral initialization before releasing the reset signal.
Is the ISL88002IE17Z-T pin-compatible with other members of the ISL8800x family?
Yes - the ISL88002IE17Z-T shares identical 3-lead SC-70 pinout and footprint with all ISL88001/ISL88002/ISL88003 variants in the same package, including ISL88001IE17Z-T (push-pull) and ISL88003IE17Z-T (push-pull high-active). This allows drop-in substitution within the same family when output logic or drive type must be changed without PCB revision.
