PMIC - Supervisors

1. Overview

Power Management IC Supervisors (PMIC-Supervisors) are semiconductor devices that monitor and control power systems in electronic equipment. They provide critical functions including voltage monitoring, current limiting, thermal protection, and system reset control. These ICs ensure reliable operation by preventing damage from power anomalies, making them essential in modern electronics such as smartphones, automotive systems, and industrial equipment.

2. Main Types & Functional Classification

Type	Functional Features	Application Example
Voltage Monitors	Track supply voltages and trigger resets during under/over-voltage conditions	Server power supplies
Reset Controllers	Generate system resets during power instability	Embedded systems
Sequencers	Manage power-up/down order for multiple rails	FPGA power management
Watchdog Timers	Monitor processor activity and trigger resets on software faults	Industrial controllers
Thermal Supervisors	Shutdown systems during overheating conditions	Power amplifiers

3. Structure & Composition

PMIC-Supervisors typically feature: - Voltage reference circuits - Analog comparators - Digital control logic - Temperature sensing elements - Multiple input/output channels - Standard packages (SOT23, TSSOP, QFN) Advanced devices integrate EEPROM for customizable thresholds and response times.

4. Key Technical Specifications

Parameter	Importance
Voltage Monitoring Range	Determines compatibility with different power rails
Threshold Accuracy	Affects system reliability (typical 1-5%)
Response Time	Speed of fault detection (10 s-10ms range)
Supply Current	Impacts power efficiency
Operating Temperature	Defines environmental suitability
Package Type	Enables application-specific integration

5. Application Fields

Consumer Electronics: Smartphones, laptops
Automotive: ECU systems, battery management
Industrial: PLCs, motor drives
Telecom: Base stations, routers
Medical: Diagnostic equipment, patient monitors

6. Leading Manufacturers & Products

Manufacturer	Key Product	Features
Texas Instruments	TPS3808	Low-power voltage supervisor with adjustable delay
STMicroelectronics	STM6600	High-accuracy multi-voltage monitor
Infineon	TLE4268	Automotive power supervisor with watchdog
