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 IR-
CUT 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.
