Product details
Overview
ISL88002IE16Z-T7A from Renesas Electronics is an ultra-low-power, open-drain voltage supervisor IC designed for precise 1.58V supply rail monitoring in battery-powered and space-constrained systems. It delivers ±1.2% threshold accuracy, 160nA supply current at 1.8V, 190ms power-on reset timeout, and valid reset assertion down to VDD = 1V. It is deployed in portable microcontroller systems requiring reliable brownout protection with minimal quiescent power draw.
For engineers reviewing the ISL88002IE16Z-T7A datasheet, ISL88002IE16Z-T7A pinout, ISL88002IE16Z-T7A application, or ISL88002IE16Z-T7A equivalent, key selection criteria include its SC-70-3 package footprint, open-drain RST output requiring external pull-up, 1.58V fixed trip point, industrial temperature range (–40°C to +85°C), and compatibility with low-voltage logic interfaces.
Technical Context
The ISL88002IE16Z-T7A implements a factory-programmed 1.58V voltage threshold comparator with 1% hysteresis to prevent noise-induced reset chatter. Its internal POR circuit asserts reset at VDD ≥ 1V and holds it for a guaranteed 140–260ms timeout after VDD exceeds VTHVDD.
As an open-drain supervisor, the RST pin sinks current when active (LOW) and requires an external pull-up resistor (5kΩ–100kΩ) to interface with µP reset inputs. It operates across 1.8V–2.75V supply range and maintains 160nA typical IDD at 1.8V, enabling multi-year battery life in always-on monitoring applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 1.58V nominal, ±1.2% accuracy - ensures precise detection of 1.58V rail collapse without false triggers. |
| Supply Current | 160nA typical at 1.8V - enables decade-scale battery operation in IoT sensors and wearables. |
| POR Timeout | 190ms typical - guarantees sufficient stabilization time for low-voltage MCUs before release from reset. |
| Operating Voltage | 1.8V to 2.75V - supports direct integration with 1.8V/2.5V logic domains and Li-ion/Li-Po battery systems. |
| Reset Output Type | Active-low open-drain - allows wired-OR reset bus sharing and flexible voltage-level translation via pull-up. |
| Temperature Range | –40°C to +85°C - qualified for industrial and automotive cabin-adjacent embedded applications. |
| Package | 3-lead SC-70 (P3.049) - 2.0mm × 1.25mm footprint saves >50% board area vs. SOT-23. |
Pinout & Package
ISL88002IE16Z-T7A is housed in a Pb-free, RoHS-compliant 3-lead SC-70 plastic package (JEDEC MO-203AA, Renesas pkg drawing P3.049), measuring 2.0mm × 1.25mm × 0.95mm with 0.65mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for internal comparator and reset logic; must be connected to system ground plane for stable threshold operation. |
| 2 | RST | Active-low open-drain reset output; requires external pull-up resistor (5kΩ–100kΩ) to VDD or higher logic rail for proper µP reset signaling. |
| 3 | VDD | Power supply input and monitored voltage source; supplies IC bias and serves as the sensed rail - no separate sense pin required. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply current | 160nA typical at 1.8V - extends battery life in maintenance-free remote sensors and medical patches. |
| ±1.2% threshold accuracy | Guaranteed over –40°C to +85°C - eliminates need for external calibration in production test. |
| No external components | Self-contained supervision - removes BOM cost and layout risk of RC timing networks or discrete comparators. |

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 | 1.63V threshold, SOT-23-3 package, 1.2µA supply current - 7.5× higher quiescent power than ISL88002IE16Z-T7A. | Targeted at general-purpose 3.3V/5V systems; less suitable for sub-2V battery monitoring due to higher VTH and IDD. | Select when legacy MAX809 footprint compatibility is required and 1.63V trip point matches design margin. |
| TPS3801K33DBVR | 1.65V threshold, SC-70-3 package, 350nA supply current - 2.2× higher IDD, same package size and open-drain output. | Optimized for TI ecosystem designs; includes watchdog timer option not present in ISL88002IE16Z-T7A. | Choose when additional watchdog functionality is needed alongside voltage supervision, accepting higher current draw. |
Compared with MAX809SEUR+T and TPS3801K33DBVR, the ISL88002IE16Z-T7A offers the lowest quiescent current (160nA) and tightest threshold accuracy (±1.2%) in SC-70-3, making it optimal for long-life, low-voltage battery systems where every nanoamp matters.

FAQ
What is the exact reset threshold voltage of the ISL88002IE16Z-T7A?
The ISL88002IE16Z-T7A has a nominal reset threshold voltage of 1.58V, with guaranteed accuracy of ±1.2% over the full industrial temperature range (–40°C to +85°C). At +25°C, the typical value is 1.580V, and the min/max limits are 1.537V and 1.623V respectively, as specified in the FN6174 datasheet Electrical Specifications table.
Does the ISL88002IE16Z-T7A require an external pull-up resistor on the RST pin?
Yes, the ISL88002IE16Z-T7A features an open-drain RST output and requires an external pull-up resistor between the RST pin and the target logic rail (typically VDD or a higher voltage). The datasheet recommends values from 5kΩ to 100kΩ; 10kΩ is commonly used to balance speed and current consumption in most ISL88002IE16Z-T7A implementations.
What is the minimum supply voltage at which the ISL88002IE16Z-T7A can assert a valid reset signal?
The ISL88002IE16Z-T7A guarantees valid reset assertion down to VDD = 1.0V. This means that even as the monitored supply collapses toward depletion, the device continues to generate a clean, well-defined reset signal - a critical capability for graceful shutdown in battery-powered ISL88002IE16Z-T7A applications.
Is the ISL88002IE16Z-T7A pin-compatible with other members of the ISL8800x family?
Yes, the ISL88002IE16Z-T7A shares identical pinout and package (SC-70-3) with all ISL88001/ISL88002/ISL88003 variants in the IE suffix series, including ISL88001IE16Z-T7A (push-pull) and ISL88003IE16Z-T7A (push-pull). Only the RST output type differs - ISL88002IE16Z-T7A uses open-drain, while ISL88001/ISL88003 use push-pull - so PCB layout is reusable across the family.
What is the power-on reset timeout duration for the ISL88002IE16Z-T7A?
The ISL88002IE16Z-T7A provides a typical power-on reset timeout of 190ms, with guaranteed minimum and maximum values of 140ms and 260ms respectively over temperature. This timeout begins when VDD rises above 1V and ensures the monitored system remains held in reset until the supply stabilizes - a key timing parameter verified in Figure 4 of the FN6174 datasheet for the ISL88002IE16Z-T7A.
