Click here for production status of specific part numbers. General Description The MAX25615 is a high-speed MOSFET driver IC for automotive applications. The driver is capable of sinking 7A and sourcing 3A peak currents. The IC, which is an enhancement over MAX5048 devices, has inverting and noninverting inputs that provide greater flexibility in controlling the MOSFET. It also features two separate outputs working in complementary mode, offering flexibility in controlling both turn-on and turn-off switching speeds. The IC has internal logic circuitry that prevents shootthrough during output-state changes. The logic inputs are protected against voltage spikes up to +16V, regardless of V+ voltage. Propagation delay time is minimized and matched between the inverting and noninverting inputs. The IC has a very fast switching time, combined with short propagation delays (12ns typ), making it ideal for highfrequency circuits. The IC operates from a +4V to +15.5V single power supply and typically consumes 0.5mA of supply current. The MAX25615 has standard TTL input logic levels. 7A Sink, 3A Source, 12ns, SOT23 MOSFET Driver ●● Automotive Ready: AEC-Q100 Qualified ●● Independent Source and Sink Outputs ●● +4V to +15.5V Single Power-Supply Range ●● 7A Peak Sink Current ●● 3A Peak Source Current ●● Inputs Rated to +15.5V, Regardless of V+ Voltage ●● 12ns Propagation Delay ●● Matched Delays Between Inverting and Noninverting Inputs Within 500ps ●● TTL Logic-Level Inputs ●● Low-Input Capacitance: 10pF (typ) ●● Thermal-Shutdown Protection ●● Small SOT23 Package Allows Routing PCB Traces Underneath ●● -40°C to +125°C Operating Temperature Range The MAX25615 is available in a 6-pin SOT23 package and operates over the -40°C to +125°C temperature range.

Continuous Power Dissipation (Ta = +70°C) *As per JEDEC 51 standard. Note 1: Continuous output current is limited by the power dissipation of the package. Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board. For detailed information on package thermal considerations, refer to http://www.maximintegrated.com/thermal-tutorial. Stresses beyond those listed under “Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or...

7A Sink, 3A Source, 12ns, SOT23 MOSFET Driver IN+ Detailed Description Logic Inputs The MAX25615's logic input is protected against voltage spikes up to +16V, regardless of the V+ voltage. The low 10pF input capacitance of the inputs reduces loading and increases switching speed. This device has two inputs that give the user greater flexibility in controlling the MOSFET. Table 1 shows all possible input combinations. Connect IN+ to V+ or IN- to GND when not used. Table 1. Truth Table Alternatively, the unused input can be used as an on/off control input (Table 1).

7A Sink, 3A Source, 12ns, SOT23 MOSFET Driver Applications Information Supply Bypassing, Device Grounding, and Placement Ample supply bypassing and device grounding are extremely important because when large external capacitive loads are driven, the peak current at the V+ pin can approach 3A, while at the GND pin, the peak current can approach 7A. Vcc drops and ground shifts are forms of negative feedback for inverters and, if excessive, can cause multiple switching when the IN- input is used and the input slew rate is low. The device driving the input should be referenced to the IC's GND...
