TI's LM74502-Q1 Evaluation module, LM74502Q1EVM, is a two-channel EVM that helps designers evaluate the operation and performance of the LM74502-Q1 in channel 1 and LM74502H-Q1 in channel 2 respectively. This evaluation module demonstrates how LM74502-Q1 drives external back-to-back connected N-channel MOSFETs to realize reverse polarity protection and load disconnect feature in case of overvoltage and undervoltage events. LM74502-Q1 has a gate drive strength of 60 μA, which makes it suitable for use in applications that need inherent inrush current control. On the other hand, LM74502H-Q1 has a faster gate drive of 11-mA peak, which makes it suitable for applications which need fast turn-on and turn-off of external MOSFET switch. With the enable pin low during the standby mode, both the external MOSFETs and controller is off and draws a very low 1 μA of current.
