It monitors current on up to four independent rails. Supply span is 3 V to 28 V, bandwidth 2 MHz, slew rate 10 V/µs, temperature range -40°C to 125°C. ## Supply voltage range and power budget Minimum supply is 3 V, maximum 28 V. Each channel draws 1 mA supply current, total 4 mA. ## Bandwidth and response time The 2 MHz -3 dB bandwidth supports current monitoring in switching regulators switching at a few hundred kilohertz, where the sense amplifier must track the inductor current waveform. The 10 V/µs slew rate ensures the output can swing quickly when a fault current appears, which matters for overcurrent detection circuits that need to trigger a shutdown within a few microseconds.","metaTitle":"MAX4378HAUD+ Current Sense Amplifier, 14-TSSOP, 2 MHz","metaDescription":"MAX4378HAUD+ quad current-sense amplifier in 14-TSSOP tube. 3 V to 28 V supply, 2 MHz bandwidth, 10 V/µs slew rate, -40°C to 125°C.
