Product details
Overview
ISL88013IH522Z-T7A from Renesas (formerly Intersil) is a 5-lead SOT-23 voltage supervisor IC with fixed 2.19V VDD monitoring, watchdog timer (1.6s normal / 51s start-up timeout), complementary active-low and active-high reset outputs, and manual reset input - used for reliable power-on reset and brownout protection in microcontroller-based embedded systems.
For engineers reviewing the ISL88013IH522Z-T7A datasheet, ISL88013IH522Z-T7A pinout, ISL88013IH522Z-T7A application, or ISL88013IH522Z-T7A equivalent, key selection criteria include ±1.5% threshold accuracy over temperature, ultra-low 5.5µA supply current, reset validity down to VDD = 1V, immunity to supply transients, and dual RST/RST outputs for flexible system-level reset signaling.
Technical Context
The ISL88013IH522Z-T7A implements a precision bandgap-based voltage reference and comparator architecture to monitor VDD against a factory-trimmed 2.19V threshold (±1.5% over −40°C to +85°C). It integrates a watchdog timer with independent start-up (51s) and normal (1.6s) timeout modes, cleared by WDI edge transitions or MR assertion.
Reset assertion logic combines POR timing (200ms nominal), hysteresis (22mV at 2.19V), and dual push-pull (RST) and open-drain (RST/MR) outputs. The device requires no external components for basic operation and asserts reset when VDD falls below VTHVDD or during watchdog timeout, manual reset, or power-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Threshold | 2.19V ±1.5% - factory-trimmed trip point for primary supply monitoring; ensures accurate brownout detection across industrial temperature range. |
| Supply Current | 5.5µA typical at 5V - enables long battery life in portable equipment without compromising supervision reliability. |
| Watchdog Timeout | 1.6s normal / 51s start-up - prevents premature reset during boot while ensuring runtime fault recovery. |
| Reset Validity | Down to VDD = 1V - guarantees functional reset assertion even during deep brownout conditions. |
| Hysteresis | 22mV at 2.19V - suppresses noise-induced false resets on monitored supply rail. |
| Reset Delay | 200ms (tPOR) - holds processor in reset until supply stabilizes post-power-up. |
| Output Types | Complementary RST (push-pull high) and RST/MR (open-drain low) - supports direct interface to both active-high and active-low reset domains. |
Pinout & Package
Package: 5-lead SOT-23 (Pb-free, RoHS-compliant, JEDEC MO178AA / EIAJ SC-74 compliant; dimensions per drawing P5.064).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - RST/MR | Combined active-low reset output & manual reset input | Open-drain output asserted LOW during reset; debounced active-low input accepts push-button or controller signal to force system reset. |
| 2 - GND | Ground reference | System ground connection for all internal comparators, reference, and output drivers. |
| 3 - RST | Active-high reset output | Push-pull output driven HIGH during reset; directly interfaces with µP/µC reset pins requiring active-high assertion. |
| 4 - VDD | Supply voltage and monitored input | Primary power input (2.0–5.5V) and monitored rail; compared against 2.19V threshold for brownout detection. |
| 5 - WDI | Watchdog timer input | Edge-sensitive input that clears internal 1.6s timer on rising/falling transitions; failure to toggle within timeout triggers reset. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed 2.19V VDD monitoring | Factory-trimmed threshold eliminates need for external resistor dividers; ±1.5% accuracy ensures consistent brownout response across temperature. |
| Dual RST outputs | Simultaneous active-high (RST) and active-low (RST/MR) signals enable drop-in compatibility with diverse host processor reset architectures. |
| Watchdog with dual timeout modes | 51s start-up window avoids false triggers during OS/FPGA initialization; 1.6s runtime timeout detects software hangs without firmware overhead. |
| Manual reset with debounce | Hardware-debounced MR input rejects switch bounce; 1µs minimum pulse width simplifies push-button integration. |
| Ultra-low quiescent current | 5.5µA typical consumption minimizes impact on battery-powered systems while maintaining full supervision functionality. |

FAQ
What is the exact voltage threshold and accuracy of the ISL88013IH522Z-T7A?
The ISL88013IH522Z-T7A has a factory-programmed VDD voltage threshold of 2.19V with ±1.5% accuracy over the full industrial temperature range (−40°C to +85°C), as specified in the FN8093 datasheet Table "VTHVDD" for part marking AHS. This value is trimmed during production and does not require external calibration.
Does the ISL88013IH522Z-T7A support watchdog functionality, and what are its timeout values?
Yes, the ISL88013IH522Z-T7A includes a watchdog timer with two distinct timeout modes: a 51s start-up timeout (to accommodate system boot) and a 1.6s nominal normal-mode timeout (to detect runtime software hangs). These values are fixed and do not require external components, as confirmed in the "WATCHDOG TIMER" section of the FN8093 datasheet.
What are the reset output configurations supported by the ISL88013IH522Z-T7A?
The ISL88013IH522Z-T7A provides complementary reset outputs: an active-high push-pull RST pin and an active-low open-drain RST/MR pin. This dual-output architecture allows direct interfacing with microcontrollers requiring either reset polarity without external level-shifting or pull-up components.
Can the ISL88013IH522Z-T7A monitor a second voltage rail besides VDD?
No - the ISL88013IH522Z-T7A monitors only the VDD supply rail at its fixed 2.19V threshold. Unlike the ISL88012/ISL88014/ISL88015 variants, it does not include a VMON pin or adjustable monitoring capability. Its pinout (WDI, not VMON) and functional block diagram confirm single-rail supervision.
What package type and lead finish does the ISL88013IH522Z-T7A use?
The ISL88013IH522Z-T7A uses a 5-lead SOT-23 plastic package (JEDEC MO178AA / EIAJ SC-74 compliant) with Pb-free (RoHS-compliant) 100% matte tin plating (e3 termination finish), as documented in the "Ordering Information" table and "Package Outline Drawing P5.064" of the FN8093 datasheet.
