3-Pin Microprocessor Reset Circuits

ELECTRICAL CHARACTERISTICS (continued)

(VCC = full range, TA = -40°C to +105°C (SOT23) or TA = -40°C to +125°C (SC70), unless otherwise noted. Typical values are at TA =

+25°C, VCC = 5V for L/M/J versions, VCC = 3.3V for T/S versions, VCC = 3V for R version, and VCC = 2.5V for Z version.) (Note 1)

PARAMETER

RESET Output Voltage High

(push-pull active high, MAX810)

SYMBOL

CONDITIONS

VOH 1.8V < VCC < VTH min, ISOURCE = 150µA

MIN

0.8VCC

TYP

RESET Open-Drain Output

Leakage Current (MAX803)

(Note 3)

VCC > VTH, RESET deasserted

Note 1: Production testing done at TA = +25°C; limits over temperature guaranteed by design only.

Note 2: RESET output for MAX803/MAX809; RESET output for MAX810.

Note 3: Guaranteed by design, not production tested.
