MAX6397-ATA-T中文资料美信数据手册PDF规格书

General Description

The MAX6397/MAX6398 are small, high-voltage overvoltage protection circuits. These devices disconnect the output load or limit the output voltage during an input overvoltage condition. These devices are ideal for applications that must survive high-voltage transients such as those found in automotive and industrial applications.

Features

♦ 5.5V to 72V Wide Supply Voltage Range

♦ Overvoltage Protection Controllers Allow User to Size External n-Channel MOSFETs

♦ Internal Charge-Pump Circuit Ensures MOSFET Gate-to-Source Enhancement for Low RDS(ON) Performance

♦ Disconnect or Limit Output from Input During Overvoltage Conditions

♦ Adjustable Overvoltage Threshold

♦ Thermal-Shutdown Protection

♦ Always-On, Low-Current (37µA) Linear Regulator Sources Up to 100mA (MAX6397)

♦ Fully Specified from -40°C to +125°C (TJ)

♦ Small, Thermally Enhanced 3mm x 3mm TDFN Package
