Microchip Technology

The MIC49500 is an ultra-high-bandwidth, low-dropout, 5.0A voltage regulator ideal for powering core voltages of low-voltage microprocessors. The MIC49500 implements a dual supply configuration allowing for very low output impedance and very fast transient response. The MIC49500 requires a bias input supply and a main input supply, allowing for ultra-low input voltages on the main supply rail. The input supply operates from 1.4V to 6V and the bias supply requires between 3V and 6V for proper operation. The MIC49500 can regulate to an output voltage as low as 0.7V, making it an ideal product for low-voltage to low-voltage conversion. The MIC49500 requires a minimum of output capacitance for stability, working optimally with any type of capacitor, including small ceramic capacitors. Available in fixed output voltages from 0.9V to 1.8V and adjustable output voltages down to 0.7V, the MIC49500 comes in both 7-pin S-Pak and TO-263 packages. The MIC49500 is rated to the full operating temperature range of -40°C to 125°C junction temperature.

MIC5014 and MIC5015 MOSFET gate drivers are designed for gate control of N-channel, enhancement-mode, power MOSFETs used as high-side or low-side switches. The MIC5014/5 can sustain an on-state output indefinitely. The MIC5014/5 operates from a 2.75 V to 30 V supply. In high-side configurations, the driver can control MOSFETs that switch loads of up to 30 V. In low-side configurations, with separate supplies, the maximum switched voltage is limited only by the MOSFET. The MIC5014/5 has a TTL compatible control input. Non-inverting and inverting configurations available: MIC5014: Non-Inverting MIC5015: Inverting. The MIC5014/5 features an internal charge pump that can sustain a gate voltage greater than the available supply voltage. The gate driver is capable of turning on a logic-level MOSFET from a 2.75 V supply or a standard MOSFET from a 5 V supply. The gate-to-source output voltage is internally limited to approximately 15 V. The MIC5014/5 is protected against automotive load dump, reversed battery, and inductive load spikes of 20 V. The drivers overvoltage shutdown feature turns off the external MOSFET at approximately 35 V to protect the load against power supply excursions. The MIC5014 is an improved pin-for-pin compatible replacement in many MIC5011 applications. The MIC5014/5 is available in plastic 8-pin DIP and 8-pin SOIC packages.

The MIC5019 is a high-side MOSFET gate driver with integrated charge pump designed to switch an N-Channel enhancement type MOSFET control signal in high-side or low-side applications. The MIC5019 operates from a 2.7 V to 9 V supply, and generates gate voltages of 9.2 V from a 3 V supply, and 16 V from a 9 V supply. The device consumes a low 77 µA of supply current and less than 1 µA of supply current in shutdown mode. In high side configurations, the source voltage of the MOSFET approaches the supply voltage when switched on. To keep the MOSFET turned on, the MIC5019's output drives the MOSFET gate voltage higher than the supply voltage. The MIC5019 is available in an ultra-small 4-pin 1.2 x 1.2 mm Thin QFN Package and is rated for -40°C to +125°C junction temperature range.
