Hi All,
My project is using Masking Chip IC GPC11768A1, Whose IC operate VDD is 2.4v ~5.5v. During the design state, The project will use Kernal chip IC GPC11001A + 8MB Flash IC ! The project is a toy, which have two DC motor control four direction. OK, the problem is when use Kernal chip IC + Flash(IC VDD:2.2v~3.6v) ,The function of the toy is ok even though at the low battery voltage 3.6v. When use Masking Chip IC GPC11768A1,it will reset when the battery voltage <5.34v (Battery initial voltage is 6.4v ). We still find why cause that, Pls share your thinking.
Toy Project describe:
1. IC VDD: 3.6v LDO output
2. the system currently is Ipeak around 3.4A
3. Kernal chip + Flash IC VDD:2.2V~3.6v, it's still ok when LDO output is 1.9v. It wouldn't reset even though motor turn slow.
4. Masking Chip IC VDD: 2.4v~5.5v . Battery voltage will drop when two motor turn,and Toy will reset.
