LOW POWER 2 OUTPUT SYSTEM RESET IC SERIES
DESCRIPTION
The M62001~8 are semiconductor integrated circuits whose
optimum use is for the detection of the rise and fall in the
power supply to a microcomputer system in order to reset or
release the microcomputer system.
The M62001~8 carry out voltage detection in 2 steps and
have 2 output pins.As Bi-CMOS process and low power
dissipating circuits are employed,they output optimum signals
through each output pin to a system that requires RAM
backup, As output signals,interruption(INT) and compulsive
reset(RESET) signals are available.The interruption
signal(INT) is used to alter the microcomputer from normal
mode to backup mode and vice versa. these output signals are
classified into pulse type(M62001~M62004) and hold type
(M62005~M62008).
FEATURES
• Bi-CMOS process realizes a configuration of low current
dissipating circuits.
Circuit current
Icc=5µA(Typ.,normal mode,Vcc=5.0V)
Icc=1µA(Typ.,backup mode,Vcc=2.5V)
•Two-step detection of supply voltage
Detection voltage in normal mode (2 types)
Vs=4.45V/4.25V(Typ.)
Detection voltage in backup mode
VBATT=2.15V(Typ.)
•Two outputs
Reset output (RESET):Output of compulsive reset signal
Interruption output(INT):Output of interruption signal
•Two types of output forms:CMOS and open drain
•Two types of interruption output (INT) signals
Pulse type (M62001~M62004)
Hold type
(M62005~M62008)
•Two types of outline packages
5-pin plastic SIP (single in-line package)
8-pin plastic SOP (mini flat package)
•Output based on RAM backup mode (See the timing chart.)
