Dual 4A low-side driver for N-channel MOSFETs
The MAX17602AUA+ is a dual low-side gate driver from Analog Devices, designed to drive N-channel MOSFETs with a peak output current of 4A for both source and sink. This symmetric drive capability ensures fast charging and discharging of the gate capacitance, directly impacting switching losses in the power stage. Each of the two independent channels can be configured with inverting or non-inverting input logic, giving the system designer flexibility to match the control signal polarity from the PWM controller or MCU without external inversion.
Supply range and logic interface thresholds
Operating from a 4V to 14V supply rail, the driver covers the bias range of common 5V and 12V gate drive supplies used in telecom bricks, motor drives, and DC-DC converters. The 40ns typical rise time and 25ns typical fall time (into a specified load) set the switching speed ceiling. For a given MOSFET's total gate charge (Qg), these figures let the designer estimate the transition energy loss per cycle and the minimum dead-time required to avoid shoot-through.
Package, footprint, and temperature grade
Housed in the 8-uMAX-EP / 8-uSOP-EP package (3.00mm width, exposed pad), the MAX17602AUA+ requires a thermal land pattern on the PCB to sink heat from the die. Rated for operation from -40°C to +150°C junction temperature, this driver suits environments with wide thermal swings, including industrial motor enclosures and under-hood automotive electronics. The ROHS3 compliance simplifies global BOM compliance for EU and other regulated markets.
