JAJSCZ8B March 2017 – February 2018 TPS3890-Q1
PRODUCTION DATA.
The TPS3890-Q1 RESET output can be used to drive the reset (XRS) input of a microprocessor. The RESET pin of the TPS3890-Q1 is pulled high with a 1-MΩ resistor; the reset delay time is controlled by the CT capacitor and is set depending on the reset requirement times of the microprocessor. During power-up, XRS must remain low for at least 1 ms after VDD reaches 1.5 V for the C2000™ Delfino family of microprocessors. For 100-MHz operation, the Delfino TMS320F2833x microcontroller uses a supply voltage of 1.8 V that must be monitored by the TPS3890-Q1.
