DESCRIPTION

TheMAX6400/MAX6401//MAX6402/MAX6403/MAX6404/MAX6405

microprocessor (µP) reset circuits monitor power supplies in µP and

digital systems. These devices eliminate external components and

adjustments while providing excellent circuit reliability and low cost

solution. They are used to monitor 2.5 V, 3 V, 3.3 V and 5 V power

supplies. A manual reset input is also available.

MAX6400-MAX6405 assert a reset signal when the V supply

DD

voltage falls below a preset reset threshold voltage. The reset signal

remains asserted for at least 100 ms after the V rises above the

DD

reset threshold. The reset threshold are factory trimmable from 2.2 V

to 4.63 V in approximately 100 mV increments. All these parts are

guaranteed to assert a reset for V down to 1 V. They have

DD

excellent immunity to fast transients on V

.

DD

The devices vary in their output configuration. The

MAX6400/MAX6403 have push-pull, active-LOW reset output; while

the MAX6402/MAX6405 have open drain, active-LOW reset output.

The MAX6401/MAX6404 have push-pull, active-HIGH reset output.

The lower threshold MAX6400/MAX6401/MAX6402 have ultra-low

supply current of typically 500 nA, making them ideal for battery

powered applications. All six devices are available in the 4-bump

Chip-Scale (WL-CSP4) package.

TECHNICAL DISCUSSION

General discussion

Manual Reset

MAX6400–MAX6405 microprocessor (µP) supervisory ICs provide

system protection by monitoring power supply voltage and asserting

a reset signal if the supply falls below the specified threshold.

The MAX6402/MAX6405 have an active-LOW open drain output.

The MAX6400/MAX6403 have an active-LOW, push-pull output;

while the MAX6401/MAX6404 have an active-HIGH, push-pull

The manual reset input, MR is active-LOW logic. It allows the

RESET to be asserted by a pushbutton switch. A mechanical

pushbutton switch is effectively debounced by the glitch filter. The

typical glitch rejection is 100 ns. MR may be driven from an external

logic circuit since it is TTL/CMOS compatible. The minimum MR

input pulse is 1 µs for V = +1.2 V to +5.5 V. When not in use, the

APPLICATION INFORMATION

Interfacing to µPs with bi-directional reset pins

The MAX6402/MAX6405 RESET outputs are open drain and are

easily interfaced with microprocessors which have bi-directional

reset pins, such as the Motorola 68HC11. Directly connecting the

MAX6402/MAX6405 RESET output to the µP’s reset input and

System configurations with various µPs

The MAX6400–MAX6405 Series resets provide a system solution

for various µPs. Figures 7 and 8, respectively, reference the Philips

µPs which are compatible with the MAX6400/MAX6403 and

MAX6401/MAX6404 system resets.
