12-Bit 300ksps ADCs with FIFO, Temp Sensor, Internal Reference The MAX1230BCEG+T 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 (Analog Devices)
- **Part Number:** MAX1230BCEG+T
- **Package:** 24-pin QSOP (QSOP-24)
- **Operating Voltage Range:** 1.8V to 5.5V
- **Reset Threshold Accuracy:** ±1.5% (over temperature)
- **Reset Timeout Period:** Adjustable (1ms min, 140ms max)
- **Watchdog Timer:** Programmable (15.6ms to 1.6s)
- **Manual Reset Input:** Yes (active-low)
- **Power-On Reset (POR):** Yes
- **Operating Temperature Range:** -40°C to +85°C
### **Descriptions:**
The MAX1230BCEG+T is a low-power μP supervisory circuit designed to monitor system voltages, manage reset functions, and provide watchdog timer supervision. It ensures reliable operation by generating a reset signal if the supply voltage drops below a preset threshold or if the watchdog timer is not serviced within the programmed interval.
### **Features:**
- **Voltage Monitoring:** Monitors up to four system voltages (VCC and three auxiliary inputs).
- **Adjustable Reset Timeout:** Configurable reset delay via external capacitor.
- **Watchdog Timer:** Prevents system lockup with programmable timeout.
- **Manual Reset Input:** Allows external pushbutton reset control.
- **Low Quiescent Current:** Typically 50μA (reduces power consumption).
- **Power-Fail Comparator:** Early warning for impending power loss.
- **Small Form Factor:** 24-pin QSOP package for space-constrained applications.
This device is commonly used in embedded systems, industrial controls, and automotive applications requiring robust power supervision.
