I'm interested in using ADP1607 in a one cell NiMH project. I expect to have 100mA @ 3.3V on ADP1607 output.
When the reverse battery protection is shorted the device is working as expected. When the reverse battery protection (IRF7410) is active there are oscillations visible on Vin pin as shown below (@3ms):
Schematic is based on ADP1607 macromodel test fixture. I just added input protections and input capacitor. PWL file simulates one cell NiMH discharge.
First question: Do you have an idea what is happening when U2 (IRF7410) is not shorted?
Second question: Is ADP1607 protected against reverse voltage?
Thank you in advance for your help on this.
