Product details
Overview
ISL88002IE17Z-T7A from Renesas Electronics is an ultra-low-power 3-pin voltage supervisor IC with open-drain active-low reset output, 1.67V fixed threshold, ±1.2% accuracy, and 190ms power-on reset timeout. It monitors VDD supply voltage in portable/battery-powered systems and asserts reset down to 1V supply level.
For engineers reviewing the ISL88002IE17Z-T7A datasheet, ISL88002IE17Z-T7A pinout, ISL88002IE17Z-T7A application, or ISL88002IE17Z-T7A equivalent, key selection criteria include its SC-70-3 package, 160nA supply current, 1.67V trip point, open-drain RST configuration, and industrial temperature range (–40°C to +85°C).
Technical Context
The ISL88002IE17Z-T7A implements a precision bandgap-based voltage reference comparator with internal hysteresis to prevent noise-induced reset chatter. Its POR circuit activates at VDD = 1V and holds reset asserted until VDD exceeds 1.67V for ≥190ms.
As an open-drain variant in the ISL8800x family, it requires an external pull-up resistor on RST (5kΩ–100kΩ recommended) and delivers reset low during undervoltage or power-up. It shares identical threshold accuracy (±1.2%), temperature coefficient (0.48mV/°C), and supply current (160nA typ. at 1.8V) with its push-pull counterparts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 1.67V ±1.2% - precisely monitors 1.8V rail brownout with guaranteed margin |
| Supply Current | 160nA typical at 1.8V - enables multi-year battery life in always-on monitoring |
| POR Timeout | 190ms nominal - ensures stable power and oscillator startup before release |
| Reset Valid Down To | VDD = 1V - supports reliable reset assertion even during deep brownout |
| Output Type | Open-drain active-low - allows wired-OR reset bus and flexible logic-level translation |
| Package | 3-lead SC-70 (P3.049) - 1.25mm × 0.85mm footprint saves PCB area vs. SOT-23 |
| Operating Temp | –40°C to +85°C - qualified for industrial and portable equipment environments |
Pinout & Package
ISL88002IE17Z-T7A is housed in a Pb-free 3-lead SC-70 plastic package (JEDEC MO-203AA, Renesas pkg drawing P3.049), measuring 1.25mm × 0.85mm × 0.5mm with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for internal comparator and reset logic; must be low-impedance connection |
| 2 | RST | Open-drain active-low reset output; requires external pull-up (5kΩ–100kΩ) to host VDD or logic rail |
| 3 | VDD | Power supply input and monitored voltage source; supplies IC and serves as threshold reference |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 160nA typical enables decades of operation on coin-cell batteries |
| High threshold accuracy | ±1.2% over –40°C to +85°C eliminates need for calibration or trimming |
| No external components | Self-contained supervision - no capacitors, resistors, or trim pots required |
| Immunity to transients | Internal hysteresis and filtering reject fast supply glitches without false resets |
| Pb-free & RoHS compliant | NiPdAu e4 termination compatible with SnPb and lead-free reflow profiles |
Applications
| Microprocessor Power-Up Control | Portable Medical Sensor Node |
|---|---|

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 | Same 1.67V threshold, SOT-23-3 package, but 1.2µA supply current (7.5× higher) | Lacks SC-70 option; larger footprint and higher current limit use in space-constrained battery apps | Select when legacy MAX compatibility is required and 1.2µA is acceptable |
| TPS3801K33DBVR | 1.33V threshold (not 1.67V); 350nA supply current; same SC-70-3 package | Not a direct threshold match - requires redesign if 1.67V trip is system-critical | Choose only if system can accommodate lower trip point and higher current |
Compared with MAX809SEUR+T and TPS3801K33DBVR, the ISL88002IE17Z-T7A delivers the exact 1.67V trip point in the smallest footprint with lowest current - making it optimal for compact, long-life battery systems where threshold precision and quiescent power are non-negotiable.

FAQ
What is the reset output configuration of the ISL88002IE17Z-T7A?
The ISL88002IE17Z-T7A features an open-drain active-low reset output (RST pin). It pulls low during reset assertion and requires an external pull-up resistor (5kΩ–100kΩ) to a logic rail. This configuration enables wired-OR reset busing and voltage-level translation - unlike the push-pull variants ISL88001 and ISL88003.
What is the minimum supply voltage at which ISL88002IE17Z-T7A guarantees reset assertion?
The ISL88002IE17Z-T7A asserts reset down to VDD = 1V, ensuring reliable brownout detection even as supply rails sag deeply. This capability is critical for battery-powered systems where voltage decay must trigger controlled shutdown before data corruption occurs.
Does ISL88002IE17Z-T7A require external components for basic operation?
No - the ISL88002IE17Z-T7A operates autonomously with no external capacitors, resistors, or trimming components. Only an external pull-up resistor on the open-drain RST pin is required for proper logic-level interfacing, making it a true "plug-and-play" supervisor for minimal BOM designs.
How accurate is the 1.67V threshold of ISL88002IE17Z-T7A over temperature?
The ISL88002IE17Z-T7A maintains ±1.2% threshold accuracy across the full industrial temperature range (–40°C to +85°C), with a low 0.48mV/°C temperature coefficient. This eliminates need for system-level compensation and ensures consistent trip behavior in thermally variable environments.
What package type and dimensions does ISL88002IE17Z-T7A use?
The ISL88002IE17Z-T7A uses the 3-lead SC-70 package (Renesas drawing P3.049), measuring 1.25mm × 0.85mm × 0.5mm. Its compact size provides ~40% smaller footprint than equivalent SOT-23-3 devices, enabling high-density PCB layouts in wearables and miniature sensors.
