TSC1021
High-side current sense amplifier
Features
■ Wide common-mode operating range
independent of supply: 2.8 to 30 V
■ Wide common-mode surviving range:
-32 to 60 V (reversed battery and load-dump
conditions)
■ Maximum input offset voltage:
– ±1.5 mV for Tamb = 25°C
– ±2.3 mV for -40°C < Tamb < 125°C
■ Maximum total output voltage error:
– ±1.5% for Tamb = 25°C
– ±2.5% for -40°C < Tamb < 125°C
■ Maximum variation over temperature:
– dVos/dT = 8 µV/°C
– dVout/dT = 100 ppm/°C
■ Low current consumption: ICC max = 300 µA
■ -40 to 125°C operating temperature range
■ Internally fixed gain: 20 V/V, 50 V/V
■ EMI filtering
Applications
■ Automotive current monitoring
■ Notebook computers
■ Server power supplies
■ Telecom equipment
■ Industrial SMPS
■ Current sharing
■ LED current measurement
TSSOP8
(Plastic package)
Description
The TSC1021 measures a small differential
voltage on a high-side shunt resistor and
translates it into a ground-referenced output
voltage.
Thewww.DataSheet.net/ TSC1021 has been specifically designed to
deal with automotive conditions: load-dump
protection up to 60 V, reverse-battery protection
up to -32 V, ESD protection up to 4 kV and
internal filtering for EMI performance.
Input common-mode and power supply voltages
are independent: the common-mode voltage can
range from 2.8 to 30 V in operating conditions and
up to 60 V in absolute maximum ratings while the
TSC1021 can be supplied by a 5 V independent
supply line.
The TSC1021 is housed in a tiny TSSOP8
package and integrates a buffer that provides low
impedance output to ease interfacing and avoid
accuracy losses. The overall device current
consumption is lower than 300 µA.
