PRODUCTION DATA
The TPS3809xxx-Q1 device is a low-current supervisory circuit for monitoring system voltages above 2 V. The device asserts an active-low RESET signal when VDD drops below a preset threshold. The RESET output remains low until VDD returns above its threshold. The device design is also to be relatively immune to short negative transients on the VDD pin.
