The MIC4416/4417 IttyBitty™ low-side MOSFET drivers from Micrel are designed to switch an N-channel enhancement-type MOSFET from a TTL-compatible control signal in low-side switch applications. They feature low steady-state supply current, high peak output, low output resistance, and rapid rise and fall times.
The MIC4416 and MIC4417 are low‑side MOSFET driver ICs designed for TTL‑compatible control signals. The MIC4416 version is non‑inverting, while the MIC4417 version is inverting, both packaged in a 4‑pin SOT‑143 (M4) case.
Key features include operation from +4.5 V to +18 V supply, low steady‑state supply current, 1.2 A nominal peak output current, and typical output resistance of 3.5 Ω at 18 V. The devices are rated for –40 °C to +85 °C ambient temperature and include ESD protection and short‑delay switching suitable for battery‑conserved, solenoid, lamp, and SMPS applications.
| Supply Voltage Range | +4.5 V to +18 V |

It operates from +4.5 V up to +18 V.
The MIC4416 is a non‑inverting driver, while the MIC4417 is an inverting driver.
Both devices are supplied in a 4‑pin SOT‑143 (M4) package.
