VNH3ASP30

The VNH3ASP30 is designed as one kind of automotive fully integrated H-bridge motor driver that incorporates a dual monolithic high-side driver (HSD) and two lowside switches. This device provides a feedback digital diagnostic signal. The normal condition operation is explained in The speed of the motor can be controlled in all possible conditions by the PWM up to kHz.

Features of the VNH3ASP30 are:(1)Output current: 30A; (2)5V logic level compatible inputs; (3)Undervoltage and overvoltage shutdown; (4)Overvoltage clamp; (5)Thermal shut down; (6)Cross-conduction protection; (7)Linear current limiter; (8)Very low standby power consumption; (9)PWM operation up to 10 kHz; (10)Protection against loss of ground and loss of Vcc.

The absolute maximum ratings of the VNH3ASP30 can be summarized as:(1)Supply voltage: -0.3 to 40 V;(2)Maximum output current (continuous): 30 A;(3)Reverse output current (continuous): -30 A;(4)Input current (INA and INB pins): ±10 mA;(5)Enable input current (DIAGA/ENA and DIAGB/ENB pins): ±10 mA;(6)PWM input current: ±10 mA;(7)Junction operating temperature: Internally limited °C;(8)Case operating temperature: -40 to 150 °C;(9)Case operating temperature: -55 to 150 °C.

The electrical characteristics of this device can be summarized as:(1)Operating supply voltage: 5.5 to 36 V;(2)Supply current: 15 to 40 uA;(3)Static high side resistance: 23 to 60 m;(4)Static low side resistance: 11 to 30 m;(5)High side freewheeling diode forward voltage: 0.8 V to 1.1 V;(6)High side off state output current (per channel): 3 to 5 uA.
