TS19605CA20H Taiwan Semiconductor Three-Channel Linear LED Driver with Analog and PWM Dimming DESCRIPTION FEATURES TS19605CA20H is a three-channel Linear LED driver with analog and PWM dimming control. This device targets at automotive lighting applications. It provides high-side drivers for LED current configured with the maximum current up to 150mA per channel. By cascade external PNP transistor can reach up to 400mA per channel. TS19605CA20H operates with a wide input range of 4.5V to 70V and low quiescent current in standby mode. It is designed with various protection functions such as under voltage lockout (UVLO), LED-String open load voltage protection (OLP) and short circuit protection (SCP), ISET pin open/short protection and over-temperature protection (OTP). Diagnostic features are provided to meet automotive requirements. ● AEC-Q100 qualified with the following results: - Device temperature grade 1: -40°C to 125°C - Device HBM ESD classification level H1C - Device CDM ESD classification level C6 ● Wide input voltage range: 4.5V to 70V ● Max. output current: 150mA per channel - Adjustable by external resistor - Accuracy: ±4% per channel when IOX @ 200mA - Accuracy: ±6% per device when IOX @ 200mA - Up to 400mA per channel @ VDROPOUT≤1V ● Dimming function of PWM and Analog ● VREF pin for outside cascade structure to share the power dissipation with full loading ● Diagnostic functionalities (LED-string Open/Short, ISET pin Open/Short, over temperature, supply voltage) ● LED-String voltage feedback per channel for Single-LED Short Detection (SSD) ● Separate fault pin for Single-LED Short Failure ● RoHS Compliant ● Halogen-Free according to IEC 61249-2-21 APPLICATION ● Automotive LED Lighting: - Daytime Running Lamp (DRL) / Interior light - Stop or Tail / Position / Fog / Turn Light ● Industrial LED Applications ● General RGB or White LED Drivers TSSOP-20EP Pin Definition: 1.
