LM393BIDR | TI Dual-Channel Voltage Comparator | Wide Voltage 2-36V | Low Power Consumption and Fast Response

Product Overview

     The LM393BIDR from TI is a dual-channel standard comparator, part of the next-generation “B” version of the LM393 family. It features lower offset voltage, reduced supply current and faster propagation delay. It supports a wide single-supply voltage range (2 V to 36 V) and its input common-mode includes ground. The output is open-collector, compatible with TTL, MOS and CMOS logic. Ideal for power monitoring, threshold detection and sensor interface applications.

Key Features

• Wide supply voltage: 2 V to 36 V (single supply)
• Input common-mode includes ground
• Low input offset voltage: approx. 0.37 mV typical
• Low input bias current in the nA range
• Quiescent current independent of supply voltage
• Open-collector outputs compatible with TTL/MOS/CMOS logic
• Fast propagation delay: ~1 µs
• Enhanced ESD performance: 2 kV (HBM)

Applications

• Power supply voltage/current monitoring and protection
• Threshold detection and comparator circuits (e.g., light control, sensor triggers)
• Sensor interface circuits (temperature, light, humidity sensors)
• Battery/charging management systems requiring voltage comparison
• General-purpose comparators in industrial control modules, home appliances and automation equipment
