3.2 Block diagram
1
The BTN8982TA is part of the NovalithIC™ family containing three separate chips in one package: One p-
2
channel high side MOSFET and one n-channel low side MOSFET together with a driver IC, forming an
3
integrated high current half-bridge. All three chips are mounted on one common lead frame, using the chip
4
on chip and chip by chip technology. The power switches utilize vertical MOS technologies to ensure
5
optimum on state resistance.
6
Due to the p-channel high side switch the need for a charge pump is eliminated thus minimizing EMI.
7
Interfacing to a microcontroller is made easy by the integrated driver IC which features logic level inputs,
8
diagnosis with current sense, slew rate adjustment, dead time generation and protection against
9
overtemperature, undervoltage, overcurrent and short circuit. The BTN8982TA can be combined with other
10
BTN8982TA to form H-bridge and 3-phase drive configurations.
