What are the key features of MIC7221YM5 TR?
- 75 ns propagation delay with push-pull output enables direct logic-level driving without external pull-up resistors, unlike open-drain comparators
- Wide 2.2 V to 10 V supply range covers both 3.3 V and 5 V logic systems in a compact 5-pin SOT-23 footprint
- Rail-to-rail push-pull output swings fully between supply rails, maximizing noise margin when interfacing with CMOS logic inputs
What is MIC7221YM5 TR used for?
The MIC7221YM5 TR is suited for zero-crossing detection, window comparator circuits, and threshold detection in power management, motor control, and battery monitoring systems requiring fast 75 ns response times. Its push-pull output directly drives logic gates and microcontroller interrupt inputs without pull-up resistors, simplifying PCB design in 3.3 V and 5 V mixed-signal systems. Portable instruments, switching power supply feedback loops, and over-voltage protection circuits benefit from its wide supply range and small SOT-23 package.

Frequently Asked Questions
How does the push-pull output architecture of the MIC7221YM5 TR differ from open-drain comparators in practical circuit design?
Push-pull outputs like the MIC7221YM5 TR actively drive both high and low output states, eliminating the need for an external pull-up resistor required by open-drain devices. This reduces component count by 1 resistor per comparator, lowers output impedance to improve switching speed, and avoids the output voltage droop caused by resistor-capacitance time constants. The 75 ns propagation delay is fully realized without pull-up resistor sizing constraints.
For a 3.3 V battery-powered circuit, does the MIC7221YM5 TR supply range accommodate single-cell lithium operation?
The MIC7221YM5 TR requires a minimum supply of 2.2 V and a maximum of 10 V, which accommodates a single-cell lithium battery discharging from 4.2 V fully charged to approximately 3.0 V at end-of-discharge. At 3.3 V regulated supply it operates well within the rated range, and the push-pull output swings to within millivolts of both supply rails, ensuring valid CMOS logic levels above 2 V for a 3.3 V system at all battery states.
In an over-voltage protection circuit running at 5 V, what is the expected response time of the MIC7221YM5 TR to a fault condition?
At a 5 V supply, the MIC7221YM5 TR responds to an input overdrive condition in 75 ns propagation delay, activating a protection FET gate or fault latch within one tenth of a microsecond. For a switching power supply operating at 500 kHz with 2 µs cycle time, this 75 ns response allows the comparator to flag an over-voltage fault and disable the gate driver with 96% of the switching period remaining, providing adequate time for safe shutdown before energy storage elements charge to damaging levels.
