Description and Introduction

STEP-DOWN, 600 kHz PWM CONTROL or PWM/PFM SWITCHABLE SWITCHING REGULATOR CONTROLLER The part **S-8540B00FN-IMAT2G** is a **voltage detector IC** manufactured by **ABLIC Inc.** (formerly Seiko Instruments).  

### **Specifications:**  
- **Function:** Voltage detector with delay circuit  
- **Detection Voltage:** Adjustable (external resistors) or fixed options  
- **Detection Voltage Accuracy:** ±1.5% (typical)  
- **Operating Voltage Range:** 0.7V to 6.0V  
- **Quiescent Current:** 0.8µA (typical)  
- **Output Type:** CMOS push-pull  
- **Delay Time:** Adjustable via external capacitor  
- **Package:** **SNT-6A** (small, lead-free, surface-mount)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions and Features:**  
- **Low Power Consumption:** Ultra-low current consumption in standby mode.  
- **High Accuracy:** Precision voltage detection with minimal deviation.  
- **Adjustable Detection:** Supports external resistor configuration for custom voltage thresholds.  
- **Built-in Delay:** Prevents false triggering with an adjustable delay circuit.  
- **Compact Package:** Small form factor (SNT-6A) for space-constrained applications.  
- **Wide Voltage Range:** Suitable for battery-powered and low-voltage systems.  

This IC is commonly used in **battery monitoring, power management, and system reset circuits** in portable electronics.
