LT1620IGN#TRPBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1620IGN#TRPBF is a rail-to-rail current sense amplifier in a 16-lead SSOP package. It features a 0V to 32V common mode input range and provides level-shifted outputs for PWM controllers. The device includes a transconductance amplifier with an IOUT pin for loop control, and a programmable end-of-cycle comparator output (MODE). It operates on a 5V supply with typical active current of 3.8mA.

Instrumentation, Op Amps, Buffer Amps Feature Summary

Provides level-shifted current sense signals compatible with standard PWM controllers
Integrates a transconductance amplifier for precise average current programming
Includes a dedicated end-of-cycle flag output for battery charging notification

Instrumentation, Op Amps, Buffer Amps Applications

High performance controlled current battery charging circuits
High output voltage DC/DC converters
Constant current sources
Overcurrent fault protectors

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the suffix TRPBF indicates tape and reel packaging. Confirm the IGN suffix corresponds to the industrial temperature range (-40°C to +85°C) and the 16-lead SSOP package. Ensure compatibility with the required 5V VCC supply voltage during system design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high common mode voltage sensing up to 32V is required alongside low dropout operation. The integrated transconductance amplifier simplifies current mode control loops by directly interfacing with PWM controller error amplifiers without external level shifting circuitry.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1620/LT1621 family of rail-to-rail current sense amplifiers. While the LT1620 focuses on single-loop current control with an end-of-cycle flag, the LT1621 variant offers dual independent current control circuits for more complex dual-loop applications requiring simultaneous load and input current sensing.
