Product details
Overview
ICL7665SIBAZA-T from Intersil is a dual-channel CMOS micropower over/under voltage detector IC with individually programmable trip points and hysteresis, 1.3V internal bandgap reference, ±50mV VSET1–VSET2 mismatch, and 10µA maximum quiescent current across –40°C to +85°C. It operates from 1.6V to 16V supply and delivers up to 20mA sink current on OUT1/OUT2 for battery fault monitoring in portable instrumentation.
For engineers reviewing the ICL7665SIBAZA-T datasheet, ICL7665SIBAZA-T pinout, ICL7665SIBAZA-T application, or ICL7665SIBAZA-T equivalent, this page provides verified technical context, exact SOIC-8 package mapping, confirmed dual-comparator architecture with open-drain N/P-channel outputs, real-world hysteresis implementation guidance, and two validated alternative parts for over/under voltage supervision in low-power embedded systems.
Technical Context
The ICL7665SIBAZA-T integrates two independent comparators sharing a single 1.3V bandgap reference; each compares SET1/SET2 input voltage against that reference to drive open-drain N-channel (OUT1/OUT2) and P-channel (HYST1/HYST2) outputs. Trip thresholds are set externally via resistor dividers, enabling precise overvoltage and undervoltage detection with user-defined hysteresis.
It features guaranteed 10µA max supply current over full –40°C to +85°C industrial temperature range, 100ppm/°C threshold temperature coefficient (ICL7665SA variant), and 0.1mV typical ΔVSET resolution. The device avoids latchup through strict input voltage limits (GND–0.3V to V+ +0.3V) and requires external RC filtering for transient immunity during power-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 16V - supports direct connection to Li-ion, 3.3V, 5V, and 12V rails without regulation. |
| Quiescent Current | ≤10µA at –40°C to +85°C - enables multi-year operation on coin-cell batteries. |
| Reference Voltage | 1.30V ±2.5% (ICL7665SA grade) - stable internal threshold for accurate trip point setting. |
| Output Sink Current | Up to 20mA on OUT1/OUT2 - directly drives LEDs, MOSFET gates, or logic inputs without buffer stages. |
| Temperature Coefficient | 100ppm/°C - ensures <±15mV drift over –40°C to +85°C for reliable long-term voltage monitoring. |
| Input Leakage | ≤10nA at SET1/SET2 - permits use of high-value resistors (>10MΩ) for ultra-low power divider networks. |
| Propagation Delay | 55–90µs - fast enough for power-rail brownout response but slow enough to reject noise spikes. |
Pinout & Package
ICL7665SIBAZA-T is housed in an 8-lead Pb-free SOIC package (JEDEC MS-012-AA, M8.15 drawing), 3.9mm × 4.9mm body, 1.27mm lead pitch, with gull-wing leads suitable for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT1 | Open-drain N-channel output | Sinks current when SET1 voltage exceeds 1.3V; used for overvoltage alert or shutdown signal. |
| 2 - HYST1 | Open-drain P-channel output | Sources current when SET1 > 1.3V; connects to upper resistor in hysteresis network for rising-edge trip adjustment. |
| 3 - SET1 | Non-inverting comparator input | High-impedance node (≤10nA leakage) for resistor-divider feedback; sets overvoltage detection threshold. |
| 4 - GND | Analog ground reference | Return path for internal bandgap and comparators; must be low-impedance and separated from noisy digital ground. |
| 5 - V+ | Positive supply rail | Accepts 1.6V–16V; powers internal reference and comparators; absolute max = +18V. |
| 6 - OUT2 | Open-drain N-channel output | Sinks current when SET2 voltage falls below 1.3V; used for undervoltage warning or memory backup enable. |
| 7 - SET2 | Non-inverting comparator input | Independent high-Z input for second resistor divider; sets undervoltage trip point separately from SET1. |
| 8 - HYST2 | Open-drain P-channel output | Sources current when SET2 < 1.3V; configures hysteresis for falling-edge trip adjustment on undervoltage channel. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent detectors | Enables simultaneous overvoltage (OUT1/HYST1) and undervoltage (OUT2/HYST2) monitoring on same supply rail. |
| Individually programmable hysteresis | Hysteresis level set per channel via external HYSTx-connected resistors-no shared components or interaction. |
| 1.3V precision bandgap reference | Stable internal threshold eliminates need for external reference IC; accuracy maintained across full supply and temp range. |
| Ultra-low quiescent current | ≤10µA max over –40°C to +85°C allows integration into always-on battery-backed subsystems without runtime penalty. |
| SOIC-8 Pb-free RoHS package | M8.15 outline with 1.27mm pitch supports automated assembly and meets IPC/JEDEC J-STD-020 reflow requirements. |
Applications
| Battery Low-Voltage Warning | Single-Supply Power OK Monitor |
|---|---|
|
Use Scenario: Rechargeable Li-ion battery pack in handheld medical device requiring early warning before critical discharge. IC Role / Device Role / Timing Role: ICL7665SIBAZA-T monitors battery voltage via SET2 divider; OUT2 asserts low-battery flag when voltage drops below 3.3V with 50mV hysteresis. Use Value: Prevents deep discharge damage using only 10µA quiescent current-extends battery life by >20% versus discrete comparator solutions. |
Use Scenario: Industrial PLC controller needing reliable "Power OK" signal indicating stable 5V rail within ±5% tolerance. IC Role / Device Role / Timing Role: ICL7665SIBAZA-T uses SET1 for overvoltage (5.25V) and SET2 for undervoltage (4.75V); wired-OR outputs generate active-high POWER_OK. Use Value: Dual-threshold detection eliminates need for separate OV/UV ICs-reduces BOM count and PCB area by 33%. |
| AC Brownout Detection | Microprocessor Backup Memory Protection |
|
Use Scenario: Smart meter operating from AC mains with rectified DC bus; must detect sustained brownout before EEPROM write corruption. IC Role / Device Role / Timing Role: ICL7665SIBAZA-T monitors rectified DC after bulk capacitor; OUT1 triggers brownout flag when voltage falls below 10V for >100ms. Use Value: Built-in hysteresis prevents chatter during marginal line conditions-ensures clean, glitch-free interrupt assertion to MCU. |
Use Scenario: Embedded system with SRAM/RTC backed by coin cell; must disable writes when main 3.3V rail drops below safe level. IC Role / Device Role / Timing Role: ICL7665SIBAZA-T's OUT2 drives write-enable line low when 3.3V rail falls below 2.9V, blocking spurious writes during power collapse. Use Value: 55µs propagation delay guarantees write disable occurs before VCC crosses 2.7V-prevents data corruption with zero external timing components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar over/under voltage detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7032IDR | Single-supply nanosupply comparator (600nA), no internal reference; requires external 1.2V ref and dual comparators for same function. | Lacks integrated bandgap and dual-channel hysteresis control-needs ≥4 external components vs. zero for ICL7665SIBAZA-T. | Choose TLV7032IDR only if supply current <1µA is mandatory and board space allows added discretes. |
| MAX6715AUKA+T | Dedicated single-channel reset IC with fixed 2.93V threshold, 200ms reset timeout, no programmable hysteresis or dual thresholds. | Cannot implement independent OV/UV detection or custom hysteresis-only suitable for basic power-on reset. | Select MAX6715AUKA+T only for simple POR where adjustable thresholds and dual supervision are unnecessary. |
Compared with TLV7032IDR and MAX6715AUKA+T, the ICL7665SIBAZA-T uniquely delivers fully programmable dual-threshold supervision with integrated reference and per-channel hysteresis in one SOIC-8 package-reducing design effort, component count, and validation time for battery-critical and industrial power-monitoring systems.

FAQ
What is the guaranteed operating temperature range for the ICL7665SIBAZA-T?
The ICL7665SIBAZA-T is rated for –40°C to +85°C industrial temperature range, with all key parameters-including supply current (≤10µA), reference accuracy, and propagation delay-guaranteed across this span per FN3182 Rev 10.00 datasheet Section 3.
Can the ICL7665SIBAZA-T monitor both overvoltage and undervoltage on the same supply rail?
Yes-the ICL7665SIBAZA-T supports concurrent overvoltage and undervoltage detection on one rail: SET1 configures the upper trip (e.g., 5.5V), SET2 configures the lower trip (e.g., 4.5V), and both OUT1 and OUT2 can be wired-OR'd to generate a single POWER_OK signal.
Does the ICL7665SIBAZA-T require external passive components to operate?
Yes-external resistor dividers on SET1 and SET2 are mandatory to scale the monitored voltage to the 1.3V internal reference; HYST1/HYST2 also require pull-up/pull-down resistors to implement hysteresis. No capacitors or active components are needed for basic operation.
What is the maximum sink current capability of the OUT1 and OUT2 pins on the ICL7665SIBAZA-T?
OUT1 and OUT2 each support up to 20mA sink current at V+ = 15V and TA = +25°C, with saturation voltage ≤0.2V at 2mA-enabling direct drive of LEDs, small relays, or MOSFET gates without additional driver circuitry.
Is the ICL7665SIBAZA-T pin-compatible with earlier ICL7665 variants like the ICL7665SCBAZ?
No-while the ICL7665SIBAZA-T shares identical SOIC-8 pinout and functionality with other ICL7665S variants (e.g., ICL7665SCBAZ, ICL7665SAIBAZA), it is not pin-compatible with legacy ICL7665B or non-S versions due to differences in internal reference accuracy, temperature coefficient, and supply current specs.
