Vnh55050atr-e ignition controller and driver agent spot price optimization
describe
Vnh55050a-e is a full bridge motor driver designed for a wide range of automotive applications. The device includes a double monolithic high side driver and two low side switches. All switches are made of St semiconductor ® Known vipower ® M0 technology, which can effectively integrate real power MOSFET, MOSFET and intelligent signal / protection circuit. The three molds are assembled on an electrically isolated lead frame of a powerso-36 TP package. This package, designed specifically for harsh automotive environments, provides improved thermal performance due to exposed die pads.
In addition, its fully symmetrical mechanical design allows superior manufacturability at the plate level. The input signals ina and inb can directly interface with the microcontroller to select the direction and braking state of the motor. When diaga / ENA or diagb / ENB is connected to an external pull-up resistor, one leg of the bridge can be realized. Each diaga / ENA also provides a digital diagnostic feedback signal. Normal operation is also described in the truth table.
When CS_ When the dis pin is driven low or kept open, the CS pin allows the motor current to be monitored by providing a current proportional to its value. When CS_ When DIS is driven high, CS pin is in high impedance state. PWM, up to 20 kHz, allows the speed of the motor to be controlled under all possible conditions. In all cases, the low state on the PWM pin will turn off the LSA and LSB switches at the same time.
