HL5502

The HL5502 is high voltage protection wireless coil switch to protect system against positive and negative COIL pin voltage faults up to ±40V, and features low switch ON resistance, 90mΩ (typ). The device features two internal MOSFETs connected in series, therefore two power pins, COIL and AC, are completely isolated when it is disabled. HL5502 employs floating gate drive architecture to pass DC or AC up to 1MHz from either of COIL or AC pins. HL5502 is controlled through ENn pin and EN_POL pin. When ENn pin is driven low and EN_POL is tied to GND, the internal power FETs are enabled if either of VIN or VCC is higher than its under-voltage lockout threshold.The HL5502 is available in 16-pin WL-CSP package.

HL5502 is a high-voltage protection wireless coil switch designed to protect the system from the effects of ±40V coil pin voltage. This device features a low ON resistance of 90mΩ (Type) and has two internal MOSFETs in series, which are completely isolated when the coil power pin and AC power pin are disabled. HL5502 can also be used as a high-voltage load switch. The HL5502 employs a floating gate drive architecture, capable of handling DC or AC up to 1MHz through the coil or AC pins. The device is controlled via the ENn pin and EN_POL pin. When the ENn pin is driven low and EN_POL is tied to GND, if either VIN or VCC exceeds its undervoltage lockout threshold, the internal power FET is enabled.
