Overview
TPD1046F Toshiba Intelligent Power Device Silicon Monolithic Power MOS Integrated Circuit TPD1046F 2-IN-1 Low-Side Power Switch for Motor, Solenoid and Lamp Drive The TPD1046F is a 2-IN-1 low-side switch.
The IC has a vertical MOSFET output which can be directly driven from a CMOS or TTL logic circuit (e.
g.
, an MPU).
The IC is equipped with intelligent self-protection functions.
Features • Two built-in power IC chips with a structure combining a control block and a vertical power MOSFET (L2-π-MOS) on each chip.
Can directly drive a power load from a CMOS or TTL logic.
Built-in protection circuits against overvoltage (active clamp), overtemperature (thermal shutdown), and overcurrent (current limiter).
• • SOP8-P-1.
27A Weight: 0.
08 g (typ.
) • • • • Low Drain-Source ON-resistance: RDS (ON) = 0.
