TPD1011S High-side Power Switch

Pin No. 1 2 3 4 5 Symbol Function IN DIAG GND OUT VDD Input pin. Input is CMOS−compatible, with pull−down resistor connected. Even if the input is open, output will not accidentally turn on. Self−diagnosis detection pin. Goes low when overtemperature is detected or when output is short circuited with input on (high). n−channel open drain. Ground pin. Ou.

Features

l A monolithic power IC with a new structure combining a control block (Bi−CMOS) and a vertical power MOS FET (π−MOS) on a single chip. l One side of load can be grounded to a high−side switch. l Can directly drive a power load from a microprocessor. l Built−in protection against thermal shutdown and load short circuiting. Also incorporates a diagnosis function that allows diagnosis output to be read externally at load short circuiting, opening, or overtemperature. l Up to −10V of counterelectromotive force from an L load can be applied. l Low on resistance : RON = 60mΩ (max) l Low ope.
