Dual 4A low-side driver for the power stage
The Analog Devices MAX17601ATA+T is a dual-channel, low-side gate driver designed to drive N-channel MOSFETs. Each of the two independent channels delivers 4A peak source and 4A peak sink current, making it suitable for driving the large gate charge of paralleled MOSFETs or high-current switching stages in DC-DC converters, synchronous rectifiers, and motor-drive inverter legs. Supply range spans 4V to 14V, covering the common 5V and 12V bias rails found in telecom bricks, server PSUs, and industrial power supplies. The 150°C junction rating allows operation in high-ambient environments such as engine-bay electronics, downhole instrumentation, or sealed enclosures where thermal headroom is tight.
Switching speed and dead-time budget
Typical rise time of 40ns and fall time of 25ns define the switching transition window. A 15ns asymmetry favours faster turn-off, which helps reduce cross-conduction dead-time margin in half-bridge topologies. When sizing the bootstrap capacitor or the gate drive transformer, these edge rates set the minimum pulse width the driver can reproduce without pulse swallowing.
Lifecycle and sourcing posture
The MAX17601ATA+T carries an Active lifecycle status and is RoHS3 compliant. No end-of-life notice or last-time-buy window is in effect.
