Applications
The TPB76200 device is a high-side NFET driver integrated with a charge pump for a 48-V battery pack. It improves the safety of the battery pack by disconnecting the charging or discharging path at the battery-positive terminator. It avoids high-voltage broking munication ports by continuous ground. The device has a pre-charge or pre-discharge FET control. It can be used as a precharge FET control to charge a depleted battery and to slow the inrush current when a large bulk capacitor load is connected to the battery pack.
The independent enable inputs allow CHG and DSG FETs to be controlled by the battery pack analog front-end device or microcontroller.
The TPB76200 device is patible with TPB76016, which is a 17-cell battery pack analog front-end device.
