Texas Instruments TPS6521825 Power Management ICs
Texas Instruments TPS6521825 Power Management ICs are single-chip power-management ICs (PMICs) to support the i.MX 8M Mini processor. The ICs are in conjunction with the LP873347 device. The Texas Instruments TPS6521825 is characterized across a –40°C to +105°C temperature range, making it ideal for industrial applications.Features
