| MIC5016/5017 Micrel MIC5016/5017 Low-Cost Dual High- or Low-Side MOSFET Driver Final Information 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 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. +3V to +4V 10µF ON OFF ON OFF MIC5016BN V+ A Gate A V+ B Source A In A Gate B In B Source B Gnd IRLZ24 Back Light IRLZ24 • Automotive electrical load control • Battery-powered computer power management • Lamp control • Heater control • Motor control • Power bus switching Ordering Information Part Number Noninverting MIC5016BWM MIC5016BN Inverting MIC5017BWM MIC5017BN Temperature Range Package to +85°C to +85°C 16-pin Wide SOIC 14-pin Plastic DIP to +85°C to +85°C 16-pin Wide SOIC 14-pin Plastic DIP Logic Figure 1 3-Volt “Sleep-Mode” Switches with Logic-Level MOSFETs Micrel, Inc. • 1849 Fortune Drive • San Jose, CA 95131 • USA • tel + 1 408 944-0800 • fax + 1 408 944-0970 • October 1998 MIC5016/5017 MIC5016/5017 Block Diagram 1 of 2 Drivers per Package Charge Pump 15V * Input Connection Diagram * Inverting version only 1 NC 2 Source A 3 Gnd 4 Gate A 5 Source B 6 Gate B 7 NC In A 14 NC 13 V+ A 12 In B 11 V+ B 10 NC 9 NC 8 14-pin DIP Ground 1 NC 2 Source A 3 Gnd 4 Gate A 5 Source B 6 Gate B 7 NC 8 NC In A 16 NC 15 V+ A 14 In B 13 V+ B 12 NC 11 NC 10 NC 9 16-pin Wide SOIC Micrel Gate Source Pin Description Pin Number Pin Number N, J Package WM Package Pin Name V+A Input A Input B Gate A Gate B Source A Source B Pin Function Supply Pin A.
