LV8417CS
Bi-CMOS IC
Forward/Reverse Motor Driver
http://onsemi.com
Overview
The LV8417CS is a 1-channel H bridge motor driver IC. The package size is extremely small with wafer level package
(WLP). Moreover, the on-resistance is low (upper and lower total 0.27Ω typ.).
The application voltage range is wide (2.0V to 10.5V).
The H bridge of this IC is P-N composition and thereby reduces the external parts without need of charge pump.
Therefore, LV8417CS realizes reduction of mounting area which enables lower cost and smaller application size.
Functions
• H-bridge 1-channel forward/reverse motor driver
• IO max=1.0A (t≤100ms 2.0A, t≤10ms 3.8A)
• BiCDMOS process
• Built-in low voltage reset and thermal shutdown circuit
• Output ON resistance (Upper and lower total 0.27Ω; Ts=25°C, IO=1.0A)

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,
high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

Remarks
1. Current consumption when output at the VM pin is off.
2. Current consumption at the VCC pin when in all function stop.
3. Current consumption at the VCC pin when ENA=3V(IC starting time).
4. ENA, IN1 and IN2 pin have an internal pull-down resistor.
5. The saturation voltage of the bottom above an OUT pin is added, and the value broken by the current value is shown.
6. All output transistors are turned off if a low-voltage is detected for VCC.
7. All output transistors are turned off if the thermal protection circuit is activated. They are turned on again as the
temperature goes down.
8. Rising time from 10 to 90% and falling time from 90 to 10% are specified.
9. Time until it changes OUT pin voltage 10% from the time of change of input pin voltage being 50% of VCC is
specified.
