The TPM16050 is a high-voltage H-bridge driver dedicated for IR-CUT control in surveillance camera. It is optimized to control the IR-CUT with 20Ω impedance and 3.3V, 5V or 12V supply voltage. It can provide up-to 0.5-A drive current. TPM16050 can sustain max 17V supply voltage.

It also supports an external 26.9Ω/2.5W resistor in serial of supply pin VM, in order to protect low-voltage loads such as IRCUT from voltage over-stress with 12V supply. Internal protection features such as overcurrent protection, short circuit protection undervoltage lockout and over temperature improve reliability of the whole system.
