Overview
The TSX3702IPT is a micropower dual CMOS voltage comparator manufactured by STMicroelectronics. It features two independent channels in an 8-TSSOP surface-mount package. The device operates on a single supply from 2.7 V to 16 V or dual supplies of ±1.35 V to ±8 V. Key electrical parameters include a typical supply current of 8 µA, a maximum input offset voltage of 5 mV, and a maximum input bias current of 10 pA. The output stage provides push-pull capability with a channel output current of 20 mA. It supports an operating temperature range from -40 °C to +125 °C.
Feature Summary
- Micropower CMOS architecture designed for extremely low current consumption per comparator channel
- Push-pull CMOS output stage eliminates the need for external pull-up resistors
- Input common-mode voltage range includes ground potential
- High input impedance characteristic suitable for sensitive signal applications
Applications
- Battery-powered portable electronic devices requiring low quiescent current
- Industrial control systems utilizing general-purpose voltage comparison
- Automotive grade applications compatible with SO8 package specifications
Procurement Notes
Verify the specific suffix IPT corresponds to the 8-TSSOP package configuration before procurement. Confirm that the required operating temperature range aligns with the industrial specification limits. Ensure design compatibility with the push-pull output drive requirements. Check for any specific moisture sensitivity level handling instructions during assembly.
Selection Notes
Select this component when a dual-channel comparator with ultra-low power consumption is required. The push-pull output simplifies circuit design by removing external components. Consider the 8-TSSOP package size constraints for PCB layout. Verify that the 5 mV offset voltage meets the precision requirements of the target application.
Part Context
The TSX3702 belongs to the TSX series of micropower comparators, representing an improvement over the legacy TS3702 model. This series offers lower current consumption, improved input offset voltage, and enhanced ESD tolerance. The TSX3702IPT variant specifically utilizes the TSSOP-8 package format, providing a compact solution for space-constrained designs while maintaining automotive-grade reliability standards.
Replacement Considerations
The TS3702 is functionally compatible but exhibits higher current consumption. Designers should verify pin-to-pin compatibility if substituting older inventory. No other direct substitutes are confirmed in the provided documentation.
