  代理致新原装 G663-263T11U 微处理器复位IC

  General Description

  The G663 provide circuits initialization and timing supervision,primarily for DSP and processor-based systems. During power-on, RESET (RESET) is asserted when supply voltage VCC becomes higher than 1.1 V. Thereafter, the supply voltage supervisor monitors VCC and keeps RESET (RESET) active as long as VCC remains below the threshold voltage VIT+(1).

  An internal timer delays the return of the output to the inactive state to ensure proper system reset. The delay time, td, starts after VCC has risen above the threshold voltage VIT+. When the supply voltage drops below the threshold voltage VIT- (2), the outputs becomes active again. No external components are required. All the devices have a fixed-sense threshold voltage VIT- set by an internal voltage divider.

  The G663 incorporate a manual reset input MR . A low level at MR causes RESET (RESET) to become active. The product spectrum is designed for supply voltages of 2.5V, 3V, 3.3V, and 5V. The circuits are available in a SOT-23-5 package.

  Note:

  (1) VIT+ means the reset voltage of VCC from low to high

  (2) VIT- means the reset voltage of VCC from high to low
