HL8545/G

The HL8545/G are quad-channel, high side power switch with an integrated NMOS power FET and charge pump. The device integrates advanced protective functions such as load current limitation, overload active management by power limitation and overtemperature shutdown with configurable latch-off. Full diagnostics and high-accuracy current sense features enable intelligent control of the load. In reverse battery condition, the HL8545 need external ground diode to block the reverse current from ground to battery. While the HL8545G needn’t such ground diode. An active drain and source voltage clamp is built into address switching off the energy of inductive loads, such as relays, solenoids, pumps, motors, and so forth. During the inductive switching-off cycle, both the energy of the power supply (EBAT) and the load (ELOAD) are dissipated on the high-side power switch itself. With the benefits of process technology and excellent IC layout, the HL8545/G can achieve excellent power dissipation capacity, which can help save the external free-wheeling circuitry in most cases. The HL8545/G can be used as a high-side power switch for a wide variety of resistive, inductive, and capacitive loads, including the low-wattage bulbs, LEDs, relays, solenoids, and heaters. This device operates over a -40 °C to +150 °C junction temperature. HL8545/G are available in a 16-pin DFN package.
