S8822BV9 is a 100 A low-side MOSFET driver optimized for industrial motor control, HVAC system, and EV/HEV system applications. It is designed with a wide operating voltage (22 V to 80 V) and wide operating temperature (-40°C to 175°C) to provide a high functionality range to end-applications. The unique combination of an Autosync advanced protection circuitry, high shoot-through current, 100 A peaks current, enhanced EMI and ESD features allow the system designers to meet tight design requirements in these applications.

S8822BV9 has been designed for controlling the low-side MOSFETs and other high-side switches from a microcontroller using pulse-width modulation (PWM). The PWM signal from the microcontroller is applied to the IN pin and is then used to control the gate voltage of the low-side MOSFET. The MOSFET is connected between the CANH and CAND pin and the power supply voltage is connected to the VCC pin. The CANH pin is connected to the positive voltage supply and the CAND pin is connected to the ground.

The S8822BV9 has a number of features that make it suitable for a wide range of applications. The high peak current drive of up to 100 A helps to reduce power loss and switching losses. The advanced Autosync feature reduces shoot-through current on PWM transitions and provides a high degree of EMI and ESD protection. The wide operating voltage and temperature range makes the driver suitable for use in a wide range of applications. It also has a small package size of 8 mm2, making it suitable for space-limited applications.

The main working principle of the S8822BV9 is as follows. When the PWM signal is applied, the internal driver starts to discharge the low-side MOSFET gate capacitance to the ground voltage. This allows for fast switching of the low-side MOSFET and reduced power loss. The Autosync feature then triggers the high-side MOSFET and allows the circuit to complete the switching cycle quickly. The Autosync feature also enables advanced protection circuitry that reduces the risk of shoot-through current on PWM transitions. The wide operating temperature range and high peak current drive also help to ensure reliable operation in various environments.

S8822BV9 is suitable for a wide range of applications in the industrial motor control, HVAC system, and EV/HEV system. It offers the highest performance in both switching and protection due to the advanced Autosync protection circuitry and high peak current drive. The small package size and wide operating temperature range make the driver suitable for various space constrained applications. With its advanced protection and high performance features, the S8822BV9 is a perfect choice for a wide range of applications.
