These are stress ratings only and functional operation is not implied. Exposure to absolute maximum ratings for prolonged time periods may affect device reliabilityDescriptionThe IMP810 is designed as one kind of 3.0V, 3.3V and 5.0V power supply supervisor that is optimized for low-power microprocessor (P), microcontroller (C) and digital systems. This device can be used in (1)embedded controllers; (2)battery operated systems; (3)intelligent instruments; (4)wireless communication systems; (5)PDAs and handheld equipment. Also it is available in a compact 3-pin SOT23 package.
Features of the IMP810 are:(1)improved Maxim MAX809/MAX810 replacement: lower supply current is 6A and 80% lower maximum supply current; (2)monitor 5V, 3.3V and 3V supplies; (3)140ms min. reset pulse width; (4)active-low reset valid with 1.1V supply (IMP809); (5)small 3-pin SOT-23 package; (6)no external components; (7)specified over full temperature range: -40°C to 105°C.
The absolute maximum ratings of the IMP810 can be summarized as:(1)Vcc:-0.3V to 6.0V;(2)RESET, RESET:-0.3V to (Vcc+0.3V);(3)input current at Vcc:20 mA;(4)output current: RESET, RESET:20 mA;(5)rate of rise at Vcc:100 V/s;(6)power dissipation (TA=70°C):320 mW;(7)operating temperature range:-40°C to 105°C;(8)storage temperature range:-65°C to 160°C;(9)lead temperature (soldering, 10 sec):300°C.

The IMP809/IMP810 are 3.0V, 3.3V and 5.0V power supply supervisor circuits optimized for low-power microprocessor (µP), microcontroller (µC) and digital systems. The IMP809/810 are improved drop-in replacements for the Maxim MAX809/810 and feature 60% lower supply current.
A reset signal is issued if the power supply voltage drops below a preset reset threshold and is asserted for at least 140ms after the supply of IMP810 has risen above the reset threshold. The IMP809 has an active-low RESET output that is guaranteed to be in the correct state for VCC down to 1.1V. The IMP810 has an active-high RESET output. The reset comparator is
designed to ignore fast transients on VCC.
Low supply current makes the IMP809/IMP810 ideal for use in portable and battery operated equipment. The IMP809/IMP810 are available in a compact 3-pin SOT23 package.
