Datasheet
Description
The LM74700-Q1 is an automotive AEC Q100 qualified ideal diode controller that works with an external N-channel MOSFET as an ideal diode rectifier with 20mV forward voltage drop for low loss reverse protection. A wide supply input range of 3.2V to 65V enables control of many common DC bus voltages such as 12V, 24V and 48V automotive battery systems. The 3.2V input voltage supports the harsh cold cranking requirements in automotive systems. The device can tolerate negative supply voltages down to –65V and provides load protection. characteristic • AEC-Q100 qualified with the following features • Device temperature grade 1: –40°C to +125°C ambient operating temperature range • Device HBM ESD classification level 2 • Device CDM ESD classification level C4B • Provides functional safety • Can help Documentation for Functional Safety System Design • 3.2V to 65V Input Range (3.9V Startup) • -65V Reverse Voltage Rating • Charge Pump for External N-Channel MOSFET • 20mV Anode-to-Cathode Forward Voltage Drop Regulation • Enables Enable Pin Features • 1µA Shutdown Current (EN = Low) • 80µA Operating Quiescent Current (EN = High) • 2.3A Peak Gate Shutdown Current • Fast Response Reverse Current Blocking: Less than 0.75µs • Meets automotive ISO7637 transient requirements with suitable TVS diode • Available in 6-pin and 8-pin SOT-23 packages 2.90mm × 1.60mm All the evaluation(0)
