MIC5016BWM Micrel Semiconductor -Low-Cost Dual High- or Low-Side MOSFET Driver

Quick Detail:

Low-Cost Dual High- or Low-Side MOSFET Driver

Description:

MIC5016 and MIC5017 dual MOSFET drivers are designed for gate control of N-channel, enhancement-mode, power MOSFETs used as high-side or low-side switches. The MIC5016/7 can sustain an on-state output indefinitely.

The MIC5016/7 operates from a 2.75V to 30V supply. In highside configurations, the driver can control MOSFETs that switch loads of up to 30V. In low-side configurations, with separate supplies, the maximum switched voltage is limited only by the MOSFET.

The MIC5016/7 has two TTL compatible control inputs. The MIC5016 is noninverting while the MIC5017 is inverting.

The MIC5016/7 features internal charge pumps that can sustain gate voltages greater than the available supply voltage. The driver is capable of turning on logic-level MOSFETs from a 2.75V supply or standard MOSFETs from a 5V supply. Gate-to-source output voltages are internally limited to approximately 15V.

The MIC5016/7 is protected against automotive load dump, reversed battery, and inductive load spikes of –20V. The driver’s overvoltage shutdown feature turns off the external MOSFETs at approximately 35V to protect the load against power supply excursions.

The MIC5016 is an improved pin-for-pin compatible replacement in many MIC5012 applications. The MIC5016/7 is available in plastic 14-pin DIP and 16-pin SOIC pacakges.
