Product details
Overview
ISL88002IE16Z-T from Renesas is an ultra-low-power 3-pin voltage supervisor IC with open-drain active-low reset output, 1.58V fixed threshold, ±1.2% accuracy, 160nA supply current, and 190ms power-on reset timeout - used to ensure reliable microprocessor startup and brownout protection in battery-powered systems.
For engineers reviewing the ISL88002IE16Z-T datasheet, ISL88002IE16Z-T pinout, ISL88002IE16Z-T application, or ISL88002IE16Z-T equivalent, key selection criteria include reset output type (open-drain), VDD trip point (1.58V), operating temperature range (–40°C to +85°C), SC-70 package compatibility, and low-quiescent-current supervision for energy-constrained designs.
Technical Context
The ISL88002IE16Z-T implements a precision bandgap-based voltage reference comparator with internal hysteresis (1%) to prevent noise-induced reset chatter. It asserts reset when VDD falls below 1.58V (±1.2%) and holds reset active for ≥190ms after VDD rises above threshold.
Its open-drain RST output requires an external pull-up resistor (5kΩ–100kΩ) and remains valid down to VDD = 1V, enabling robust reset assertion during deep brownout conditions. The device operates across –40°C to +85°C without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 1.58V ±1.2% - factory-trimmed trip point ensures accurate monitoring of 1.6V-class rails. |
| Supply Current | 160nA at 1.8V - enables multi-year operation on coin-cell batteries in always-on monitoring. |
| POR Timeout | 190ms typical - guarantees sufficient delay for power rail stabilization before releasing reset. |
| Reset Output Type | Active-low open-drain - supports wired-OR configurations and flexible logic-level interfacing. |
| Operating Voltage Range | 1.8V to 2.75V - validated for use with 1.8V/2.5V systems where VDD ≥ threshold + margin. |
| Temperature Range | –40°C to +85°C - industrial-grade rating suitable for embedded and portable equipment. |
| Reset Valid Down To | VDD = 1V - maintains functional reset assertion even during severe undervoltage events. |
Pinout & Package
ISL88002IE16Z-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 optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground reference | IC substrate and comparator reference node; must be connected to system ground plane for stable threshold accuracy. |
| 2 - RST | Open-drain reset output | Active-low signal asserted when VDD < 1.58V; requires external pull-up to define logic HIGH level and drive strength. |
| 3 - VDD | Power supply & monitored input | Supplies IC bias and serves as the sensed rail; internally compared against 1.58V reference with hysteresis. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed 1.58V threshold | Enables precise supervision of low-voltage logic rails (e.g., 1.6V FPGA I/O, ultra-low-power MCUs) without trimming resistors. |
| 160nA quiescent current | Reduces standby power by >5× vs. legacy supervisors, extending battery life in IoT sensors and wearables. |
| 190ms POR timeout | Guarantees microcontroller core and peripherals are held in reset until power stabilizes - prevents erratic boot behavior. |
| Immunity to supply transients | Hysteresis and internal filtering suppress false resets caused by switching noise or ripple on VDD. |
| SC-70 footprint | 0.95mm height and 2.2mm × 1.35mm area minimize board space vs. SOT-23, critical for compact handheld devices. |
Applications
| Battery-Powered Wearables | Industrial Sensor Nodes |
|---|---|

IC Role / Device Role / Timing Role: ISL88002IE16Z-T monitors the 1.8V auxiliary rail powering configuration circuitry and asserts reset until stable. Use Value: Guarantees FPGA bitstream loads only after power integrity is confirmed, avoiding partial configuration failures. |
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 | 1.6V threshold (±2.5%), 1.2µA supply current, SOT-23-3 package | Higher quiescent current limits battery life in multi-year deployments; lacks SC-70 option | Select when legacy MAX809 footprint compatibility is required and power budget allows >7× higher IDD. |
| TPS3801K33DBVR | 3.3V threshold, 1.8µA supply current, same SC-70 package | Fixed 3.3V trip unsuitable for sub-2V rails; no 1.58V variant available | Choose only for 3.3V systems requiring TI's enhanced ESD rating (4kV HBM); not a functional substitute for 1.58V monitoring. |
Compared with MAX809SEUR+T and TPS3801K33DBVR, the ISL88002IE16Z-T delivers 10× lower supply current and exact 1.58V threshold alignment for emerging ultra-low-voltage MCUs - making it the sole option among the three qualified for 1.6V rail supervision with sub-200ms POR.

FAQ
What is the reset output configuration of the ISL88002IE16Z-T?
The ISL88002IE16Z-T features an active-low open-drain RST output. This requires an external pull-up resistor (5kΩ–100kΩ) to define the HIGH state and supports wired-OR reset bus architectures. Unlike push-pull variants (e.g., ISL88001), it does not drive HIGH actively - a key distinction confirmed in the FN6174 datasheet Pin Descriptions section.
What is the exact voltage threshold and accuracy of the ISL88002IE16Z-T?
The ISL88002IE16Z-T has a nominal reset threshold of 1.58V with ±1.2% accuracy over –40°C to +85°C, as specified in the Electrical Specifications table (VTHVDD for Ix16 variants). At +25°C, the typical value is 1.580V, with min/max bounds of 1.561V and 1.599V - verified in the FN6174 Rev 3.00 datasheet on page 8.
Can the ISL88002IE16Z-T operate with supply voltages below 1.8V?
Yes - the ISL88002IE16Z-T is rated for VDD = 1.8V to 2.75V per the "Supply Voltage Range" specification in FN6174 (page 8), and its reset signal remains valid down to VDD = 1V. This allows reliable assertion of reset during deep brownout, though normal operation (e.g., POR timeout generation) requires VDD ≥ 1.8V.
What package type and dimensions does the ISL88002IE16Z-T use?
The ISL88002IE16Z-T uses a Pb-free 3-lead SC-70 package (JEDEC MO-203AA, pkg drawing P3.049), with dimensions 2.20mm × 1.35mm × 0.95mm. Lead pitch is 0.65mm, and the package is RoHS-compliant with NiPdAu termination - confirmed in the Ordering Information table (page 3) and Package Outline Drawings (page 14).
How does the ISL88002IE16Z-T compare to the ISL88001IE16Z-T?
The ISL88002IE16Z-T and ISL88001IE16Z-T share identical threshold (1.58V), accuracy (±1.2%), supply current (160nA), and package (SC-70), but differ in reset output topology: ISL88002IE16Z-T uses open-drain RST, while ISL88001IE16Z-T uses push-pull RST. This makes ISL88002IE16Z-T suitable for shared reset buses, whereas ISL88001IE16Z-T drives both logic states actively - per Functional Block Diagrams (page 2) and Pin Descriptions (page 2).
