UCC3946D Ratings and Reviews

D***v

This shit broke 3,5 connector on the phone, the phone died. This thing itself suffocated a little later-fucked the transistor (which i was sent bu) sold ahuel to the edge. The kit does not include instructions, nor thermal paste with a bulb. Not advise

***AS INSRUMENTS: The UCCx946 is designed to provide accurate microprocessor supervision, including reset and watchdog functions. During power up, the device asserts a reset signal RES with VDD as low as 1 V. The reset signal remains asserted until the VDD voltage rises and remains above the reset threshold for the reset period. Both reset threshold and reset period are programmable by the user.

***AS INSTRUMENTS INCORPORATED: The UCCx946 is also resistant to glitches on the VDD line. Once RES has been deasserted, any drops below the threshold voltage need to be of certain time duration and voltage magnitude to generate a reset signal. These values are shown in Figure 1. An I/O line of the microprocessor may be tied to the watchdog input (WDI) for watchdog functions. If the I/O line is not toggled within a set watchdog period, programmable by the user, WDO is asserted. The watchdog function is disabled during reset conditions.

***INS: The UCCx946 is available in 8-pin SOIC(D), 8-pin PDIP (N) and 8-pin TSSOP(PW) packages to optimize board space.
