• Product Introduction

MC33972ATEK  Multi-switch detection interface and suppression wake-up

The 33926 is a monolithic circuit H-bridge power IC designed primarily for automotive electronic throttle control, but is suitable for current and voltage limits within any low-voltage DC servo motor control application specified in this specification.The 33926 is capable of controlling inductive loads with a current peak of 5.0 A.RMS current capability is the degree of heat dissipation depending on the provided device package.Activate the internal peak current limit (regulation) at load currents greater than 6.5 A± and the output load can be pulse width modulation (PWM-ED) at frequencies up to 20 kHz.The load current feedback feature provides a proportional (0.24% load current) output current suitable for monitoring the A/D input of a microcontroller.A status flag output reports undervoltage, overcurrent, and overtemperature fault conditions.Two independent inputs provide polarity control of the two half-bridge totem pole outputs.Two independent prohibition inputs force the H-bridge output to be three-state (high-blocking shutdown state).A change on the inverting input side IN1 and IN2 inputs low = true logic.peculiarity--------------------------------------------------------------------------------8.0 V to 28 V Continuous Operation (Transient from 5.0 V to 40 V)225 mOhm Max RDS(ON) @ 150°C (per H-Bridge MOSFET)3.0 V and 5.0 V TTL/CMOS logic compatible inputsOvercurrent limiting (regulated) by internal constant shutdown time PWMOutput Short Circuit Protection (Short VPWR or Ground)The current limiting threshold for temperature dependents is reduced所有输入有一个内部信号源/接收器，以定义默认（浮动输入），美国睡眠模式电流The product is included in Freescale's long-term product availability program, which is guaranteed to be available for at least 15 years.
