12-Bit 300ksps ADCs with FIFO, Temp Sensor, Internal Reference The MAX1230BCEG+ is a microprocessor (μP) supervisory circuit manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:
### **Specifications:**
- **Manufacturer:** Maxim Integrated
- **Part Number:** MAX1230BCEG+
- **Package:** 24-pin QSOP (QSOP-24)
- **Operating Voltage Range:** 1.8V to 5.5V
- **Reset Threshold Accuracy:** ±1.5% (typical)
- **Reset Timeout Period:** Adjustable (1ms min, 140ms max) or fixed (20ms, 140ms, 1.12s, or 4.48s)
- **Watchdog Timer:** Programmable timeout (15ms to 1.12s)
- **Manual Reset Input:** Active-low (MR)
- **Operating Temperature Range:** -40°C to +85°C
- **Power-On Reset (POR):** Monitors VCC and asserts reset when voltage drops below threshold
### **Descriptions:**
The MAX1230BCEG+ is a highly integrated μP supervisory circuit designed to monitor power supply voltages, manage reset functions, and provide a watchdog timer for microprocessor-based systems. It ensures reliable system operation by generating a reset signal if the supply voltage falls below a preset threshold or if the watchdog timer is not periodically serviced.
### **Features:**
- **Voltage Monitoring:** Monitors up to four system voltages (VCC and three additional inputs)
- **Adjustable Reset Timeout:** Configurable via external capacitor or factory-set options
- **Watchdog Timer:** Prevents system lockup by requiring periodic servicing
- **Manual Reset Input:** Allows external push-button reset control
- **Low Quiescent Current:** Typically 35μA (reduces power consumption)
- **Power-Fail Comparator:** Provides early warning of impending power failure
- **Hysteresis:** Built-in hysteresis for noise immunity on monitored inputs
- **RoHS Compliant:** Lead-free and meets environmental standards
This device is commonly used in embedded systems, industrial controls, and automotive applications where reliable power monitoring and system reset functionality are critical.
