Part Number: TPS3809
if /MR is pulled low during tpd(r), does /Reset low time keep same or increase?
If /MR is pulled low DURING t_PD(r) then /RESET will go low after td(MR). If /MR is pulled low after the device is already about to RESET due to sense input, then /MR is ignored.
In reply to Michael DeSando1:
my requirement: when I pull a pin low and then release it, /RESET pin will go low 10s and then go high, during /RESET low status, this pin is ignored, no matter it is pulled high or low.
do you know which device can meet this requirement?
In reply to Max Han:
Yes, we have several devices that do exactly that. My recommendation is TPS3890. You can also use TPS3808, TPS389x (TPS3895, TPS3896, TPS3897, TPS3898). These devices differ in output type (active low/active high, open drain/push pull) and if you require automotive grade. The key for your application is that the device is "programmable" to 10 seconds which all of these device are. If you need additional support please let me know!
