PM8841D is a high efficiency, half-bridge power module with integrated power MOSFETs to minimize losses in the low on-resistance device. The PM8841D power module is tailored for applications requiring high power density and a compact package such as domestic appliances, lights, medical equipment, and other applications.
The PM8841D is an integrated power module that combines two full-bridge MOSFETs, a bootstrap diode, and gate drivers in an isolated, thermally efficient package. This power module is designed to reduce the time and effort required by system engineers in complex designs. The module is also well-suited for hot swap applications due to its fast and controlled turn-on and turn-off times.
The PM8841D consists of two independent high-efficiency half-bridges with internal gate drivers, consisting of a 2-wire power stage, a power MOSFET and a bootstrap diode. These two independent driver channels provide high drive current with low noise and low output capacitance. The PM8841D has wide variety of over temperature protection, current protection and controlling features, such as Spread Spectrum Frequency Dip (SSFD) and Emulated Resistance Control (ERC).
The PM8841D combines an integrated half-bridge with an isolated gate driver and integrates the full power stage design onto one DSO-type package. It is then compatible with many different gate driver formats, including VS-CON, PWM and H-Bridge. The PM8841D can provide output lines up to 5A continuous current and 7A peak, and can drive up to two independent half-bridges with rise and fall times of 1.2 μs.
The PM8841D is designed to provide high efficiency output with low losses and minimal power dissipation. The MOSFETs and gate drivers are controlled via a local SPI, which provides digital control of power stage parameters, including current limit and Snubberias voltage. The PM8841D reduces system cost by minimizing system components count and overall power dissipated.
The PM8841D can be used in a variety of industrial, automotive, and consumer applications, such as domestic appliances, light fixtures, medical equipment, servo motors, engine Start-Stop technology, as well as electric vehicle applications. The PM8841D is also suitable for power module applications where high efficiency, fast response, and minimized board space is desired.
The PM8841D has an advanced gate driver design that allows for high switching speed, improved cooling, and fast rise and fall times of 1.2 microseconds. The PM8841D also offers high-side and low-side integrated current sensing for monitoring of inductor current to support the ERC and SSFD control functions.
In summary, the PM8841D is a highly-integrated, high-power, high-efficiency half-bridge power module with integrated power MOSFETs and gate drivers. It is designed for a wide range of industrial, automotive, and consumer applications requiring high power density and fast response. Its integrated gate drivers provide fast turn-on and turn-off times and the overall system can be controlled via local SPI, making it suitable for hot swap applications. Its wide variety of over temperature protection, current protection, and controlling functions make it a reliable and efficient solution for a wide range of applications.
