Application Information
Negative VCC Transients
The ASM809/ASM8091/ASM810 protect pS from brownouts
and low VCC. Short duration transients of 100mV amplitude
and 60pS or less duration typically do not cause a false
RESET.
Valid Reset with VCC under 1.1V
When VCC is under 1.1V, to ensure logic inputs connected to
the ASM809,ASM8091 RESET pin are in a known state, a
100k
pull-down resistor is needed at RESET. The value of
the resistor is not critical. A 100k
pull-up resistor to VCC at
RESET is needed with the ASM810.
Bidirectional Reset Pin Interfacing
The ASM809/ASM8091/ASM810 can interface with P / C
bi-directional reset pins by connecting a 4.7k
resistor in
series with the ASM809/ASM8091/ASM810 reset output and
the P/C bi-directional reset pin.
