Product overview
Description
The STDRIVE141 is an integrated quad half-bridge gate driver designed to control up to eight N-channel MOSFETs. The STDRIVE121 is an integrated dual half-bridge gate driver designed to control up to four N-channel MOSFETs. These devices, together with the octal half-bridge STDRIVE181, extend the STDRIVE family.
A 24-bit serial peripheral interface (SPI) is used for configuring and controlling the half-bridges. SPI status registers provide high-level diagnostic information such as supply voltage monitoring, charge pump voltage monitoring, temperature warning, and overtemperature shutdown.
Each gate driver independently monitors its external MOSFET drain-source voltage for fault conditions.
A more efficient gate current control of the external MOSFETs, called “three stages gate current,” reduces switching losses and optimizes electromagnetic interference (EMI).
The device integrates a full range of protection features, such as drain-source monitoring for short circuit detection, overtemperature warning and shutdown, timeout watchdog for MCU control, and detailed off-state diagnostic via SPI.
Both the STDRIVE141 and STDRIVE121 are hosted in a VFQFN32L package with an exposed pad.
