The MIC5018 IttyBitty™ is a high-side MOSFET driver designed to switch an N-channel enhancement-type MOSFET using a TTL-compatible control signal. This driver is suitable for high- or low-side switch applications and comes in a compact 4-lead SOT-143 package.
It operates from a supply voltage range of +2.7V to +9V and boasts extremely low off-state supply current, with a typical standby current of less than 1µA. An internal charge pump drives the gate output higher than the driver supply voltage, ensuring the MOSFET remains fully enhanced. For protection, an internal zener diode limits the gate-to-source voltage to a safe level for standard N-channel MOSFETs.
The MIC5018 can operate in both low-side and high-side configurations. In high-side applications, the driver is typically powered from the load supply voltage. In low-side configurations, it can control a MOSFET switching any voltage up to the MOSFET's rating. The gate output voltage is higher than typical 3.3V or 5V logic supplies, allowing for full enhancement of standard MOSFETs.
This device is rated for an ambient temperature range of –40°C to +85°C, making it suitable for various environmental conditions. Its features include TTL-compatible input, ESD protection, and suitability for applications requiring battery conservation and power bus switching.
