Other Parts Discussed in Thread: SN74HC244, LMR14020
Hi team
I use TPS3702 to monitor the VCC of TMS320F28062 . I connect the UV to MCU RST pin to reset the MCU when the MCU VCC is under 2.9V and connect the OV to LMR14020 EN pin and the gate of NMOS to shunt down the DCDC and SN74HC244 when the MCU VCC is over 3.6V .
1. Could you please help me to check the schematic?
2. helping me check if there is any timing problem of this design
3. helping me check if the Rpu value is appropriate
Best regards
Wesley Huang
